Hand down the best GPS tracker around!! Love it!!
Hands down, the best tracker I have ever used! I have used 4 or 5 different trackers in the past, but this one beats all the rest I have previously used by a country mile! I originally had a spare mobile phone set up with a 4G sim and a GPS app installed, and it worked OK, but the battery life on the phone wasn't great and I could only charge it whilst I had the ignition on, so after a day or so it would drain the battery life. So I looked at an alternative option. I purchased a GPS tracker (i forget the name of the brand) which i hardwired into the car via the fuse box - again, this worked OK, but it had a very buggy app and rarely showed the correct location. So I then purchased a 'mini GPS' sim tracker that claimed to work with any sim carrier...but it didn't and I could even get it to work. Lastly, before I got this device, I purchased the Vodafone curve which has a built in v-sim. Out of all the previous ones, the vodafone curve is the best, and works relatively well for a small monthly fee - but - compared to this item, the curve is nothing. Now...for THIS item...what a nice, easy and simple device that works...and very well! After unboxing, there's a slip with an activation code to register the device. Then it was just a case of downloading the devices app and plugging into the OBD port of my car. No wires. No mess. No fuss. Don't even have to worry about fiddling with a sim card as it has one built in. Don't have to worry about battery life either. It pulls through enough power without the ignition on and no reduction in battery voltage and ...it just works very well. It even has useful features in the app to enable smart security to detect vibration and you can even set it up to detect harsh cornering/braking/accellation etc. You can see exactly when the engine is started and stopped, where the car has been on each trip...and even follow the map LIVE if you wanted. Literally the only nag I had was that once I plugged the device into my OBD port, the flap door that covers my port wouldn't close as the device was sticking out. But this was a very easy and simple workaround...the guys who manufacturer this device also offer an extension OBD cable, and its relatively cheap, too. I purchased the cable, and once I installed it, I was able to hide the device in the dashboard and close the flap door. This device also detects and notifies you when it is plugged in or unplugged. I dont have a bad thing to say about it. I gave had it in the car almost a week now...and I love how simple it is to operate. The monthly subscription is 100% worth it.

Peace of mind
I purchased the obd port tracker along with the obd slim splitter cable which enabled me to hide my CarLock tracker yet still have my obd port available for use, the tracker is brilliant and is very accurate, combined with the app which shows you your driving statistics, speed, harsh braking,cornering etc, it really is a great product and gives me piece of mind knowing my car is protected 24/7 and also helps me improve my driving. I fitted this over 3 months ago and had no issues whatsoever and I carnt see any in the future it is a solid tracker and customer support is excellent, I’ve recently purchased the CarLock Bluetooth tag which enables and disables the tracker when you approach/leave your car again giving me peice of mind, I hope this helps someone who is considering buying this tracker, I say go for it you won’t regret it

Excellent and easy product to use
Decided to give this a try after having a think about it. Reading some reviews I was a bit unsure of how well it would actually perform, and the answer is quite well! So having installed it on my new Focus, just as a bit of an insight and security on where the car is and anything I should maybe be aware of if someone else is driving the car, it comes in quite handy. I connected it through a OBD splitter cable, hid the carlock device itself away, so it can't be seen, but if the car were to go into the garage they can still connect their OBD reader etc. so the carlock never gets removed. First drive, immediately as I hit the open road it was alerting me of harsh acceleration.. But what do I expect from a Focus ST... It was a bit over sensitive for a start but seems to have sorted itself out and is proving well detailed trip information and quickly to the android app. The app is fairly responsive and easy to use and understand, often a bit on the buggy side, not really sure what it would come down to, but who knows improvements are maybe yet to come. Still this doesn't let the product down as a whole. The device itself never seems to have a problem connecting through it's inbuilt sim, even when miles out of town. Which is quite good considering the 3G connectivity isn't always the best up here in the north of Scotland. Great invention and easy to install right on your drive way. Recommend!

Great idea, but doesn't quite work
Very easy to install and set up. I have been using it for around 2 weeks now. Thoughts so far, when it works it is fantastic but there are too many issues with the device. 1. Trips are not always logged. Have to contact support to resolve. Takes around 48 hrs. UPDATE* Support has fixed this problem and it is working fine. 2. Smart tag on Bluetooth does not always work. On a few occasions that smart tag has not automatically disabled the security. UPDATE* Support has resolved this problem with my iPhone. Had to enable CarLock in Motion & Fitness. 3. Driving score not logged. Have to contact support to resolve. Takes around 48 hrs. UPDATE* Support has fixed this problem and it is working fine. I am still very happy with the device. I like the logging of each trip, no more arguments about how long a journey took to drive. GPS location helps in large carparks. The vibration sensor is very sensitive, which is good in case there is a hit and run on your vehicle. The battery monitor is in real time and is useful to check your battery health. I would definitly get the extension cable, allows you to place the device in a more suitable location. I have hid mine behind a panel and secured it with cable ties. This should in theory make it harder for would be thieves to find the device and throw it away. The smart tag, still not sure about this bluetooth device. I am waiting on the battery life before making a final verdict.

Carlock tracker and phone app.
I'm very happy with this product and the peace of mind you get from knowing that if someone gets in your car (vibration detection) or starts the engine you will receive an alert on the app on your phone. You can also get alerts for harsh acceleration/braking/cornering or speeding so if someone is driving your car you will know and can track it's whereabouts in real time. It records your trips from place to place with milage, top speed and average speed. It also monitors your cars battery and let's you know if your voltage is low. Over all a good tracker.

Not fit for purpose.......Do not buy.
On paper, and according to the CarLock sales spiel, this should be a great addition to vehicle security but from my personal experience the Carlock is as much use as an ornament, or a chocolate fireguard. It has not worked properly since I installed it on my 2019MY Mercedes 450GLE. The engine start, vibration detected, and vehicle battery information alarm notifications are triggered correctly on the App, but there was no vehicle tracking, or vehicle location position recorded following the initial install. It located my home install location correctly but thereafter nothing about the vehicle usage, or its whereabouts was ever recorded. No matter how many miles I drove, or wherever I went, my vehicle was shown as never having moved off my driveway. This was despite the fact that the tracker app showed the device was was being monitored by up to 18 satellites. I reported the problem to their support team straightaway and for a month they were apparently "working" on it. I say apparently as they never bothered to update me. The only time I ever heard anything was when I chased them, which I did every few days. Even then all I ever got were platitudes "we are working on it". The silence has been deafening! I requested a replacement a number of times but this was ignored until over a month later when they agreed that I should return the unit, and they would send a replacement. Which they duly did and re-reimbursed the postage costs I installed the new unit which had exactly the same problem as the one I had returned. This time though on installation it failed to register any tracking satellites. I reported the problem to CarLock (UMTR Group), and was informed, quote "The problem is being solved and you will be advised about it soonest" unquote. A day later I was contacted again and informed, quote " We have been discussing the issue with our "R&D. They have had a deeper insight but the only conclusion is that somehow the device is not connecting and their guesstimation is that the problem is - do not get us wrong, please - in the car that seems like being heavily armored" unquote. (Their words and spelling). I have written back to them informing them that my vehicle is not armoured, or protected in any way. Its a standard Mercedes GLE 450. I had such high hopes for this device as a complement to my existing vehicle security system but I've now given up and returned it to Amazon. It might be something to do with my vehicle but the device clearly does not work. Furthermore the technical support is the worst that I have ever encountered. I would definitely not recommend.

Good at tracking, disappointing driving info
Does what's it's supposed to do, but compared to other trackers gives very little information about the driven route. It gives the top speed and average speed and that's it. If you want to know the speed at a certain point or on a particular road, then look elsewhere. The navmii tracker will tell you the speed every 5 seconds. While not needed by everyone I find it invaluable when I think I have gone too fast through a speed camera by accident. Saves the long 2 week wait!

BEST BANG FOR THE BUCK
I was in the market for getting a GPS Tracker with an alarm. I am old school, I was looking for an alarm that sounds loud and everyone can hear it. This is NEW technology, when you buy the (motion sensors ) extra. They go off as soon as the car detects any movement and the APP on your phone goes OFF LOUD. There is no excuse I did not hear the alarm. At the car there won't be any sounds. This is good because the person messing with your car will not know. Giving you time to act in which ever way you decide is safe for you. The app gives you GPS TRACKING depending on the subscription you purchase. The subscriptions are the most reasonable on the market at this moment. It also lets you set an alarm at any top speed you want. Anyone driving the car goes over that speed the alarm will go off on the APP on your cell phone. It also rates the way you drove your trip letting you know where you were speeding and where you did hard stops. The app also shows you how many miles you have driven on a monthly basis in case you want to keep track of your milage. Trips you have taken and length in time of each trip. Many more features, I just want to give you an idea on what you will get with this unit. As far as the Unit I purchased the OBDII extender and placed the unit away from my OBDII. No one knows I have the unit installed except me. Plus it leaves the OBDII open for any time you might need to access it. This unit also activates the alarm on a timer. The app lets you set up the time you want the unit to activate after you have turned off the car. I purchased the unit I also purchased sensors for each door of my vehicle as well as the tag. The TAG is one of the greatest add on I highly recommend. What the tag does is activates and deactivates the alarm automatically when you come close to your car automatically. This way you won't have to do it with your cell phone before you open your car. All in all if you want something that will not break the bank and will give you a piece of mind I will highly recommend this unit. The only thing is that in order to make this GPS ALARM work the way it is intended to don't SKIMP out on the add-ons. Buy the add ons you need because you will save on the monthly subscription and have a piece of mind. How much is a piece of mind worth it to you? Item I would highly recommend and I am not part in any way with this company. All I am is part of the CARLOCK Family.

Super produit. Très facile d'installation et très fiable dans l'utilisation. Je l'utilise pour une flotte de 14 véhicules. Cela me permet d'anticiper le mode de conduite et les frais liés à l'utilisations des véhicules. SAV très réactif et commerçants. Juste l'interface à améliorer pour la gestion de plusieurs véhicules mais cela est du détail.
