SILCA Tattico Bicycle Mini-Pump with Bluetooth Gauge Reading PSI or BAR

I don't like long and detailed reviews, but this one required some explaining.I hoped that this very expensive product would fill my need for both an emergency road and trail pump, and a precision pump/gauge for filling tubeless tires with great accuracy. In the latter case I am disappointed, because the pump's two most important features simply don't work well. (First, though, I'll say the pump works fine for emergencies. It'll pump up a typical road tire quickly. Plus, it looks like it will last awhile, and the mounting bracket is awesome. If this is all you need, buy the non-bluetooth version of the same pump.)Unfortunately for me, who bought the bluetooth version, that feature is unreliable. At first it worked fine, and then one day while I was pumping up a tire, the brightly displayed pressure reading on my iPhone screen went blank, and the app was gone! When I tried to reload the app, I received a message saying it was no longer available in North America. I almost returned the pump, but I needed it for the road, and I assumed the app would be reinstated. It was, and I continued to use the pump until, literally the day after the return window closed, the bluetooth feature quit working, period. The app still works, but it searches and searches for input from the pump, and never receives it. So now I have a REALLY expensive, exquisitely made emergency pump with a defective pressure sensor.I said there were two features that don't work well for my purposes. The second is the the head unit, which attaches to the Presta valve. Upon disengagement from the valve, it releases too much air from the tire for the gauge to be accurate (when the gauge works). For example, the gauge might read 35 psi when disengaged, but, after a loud hiss, subsequent re-engagement might reveal the tire to be holding 30 psi. This doesn't happen every time, but I'd say 4 out of 5 times. My gold standard for achieving accurate and repeatable tire pressure is a floor pump used in conjunction with an Efficient Velo Tools gauge. This isn't that, and in fairness, Silca doesn't claim it is. Unfortunately, it's not very close. Lesson learned, and I still have a nice emergency pump.

Got this pump today, so I can't speak for its longevity.Works as advertised. Easy to mount and pair with iPhone 7. I checked my pressure and both tires were low 70 PSI. Got both up to 90 pretty quick. I probably wouldn't want to pump much above that, as the resistance gets tough around 85 PSI, but it is plenty if you are fixing a flat.Hidden flexible hose ensures that you aren't applying pressure to the valve stem as you pump.Material seems sturdy. Heat build up is minimal.So far, so good.

I purchased this pump (with version with bluetooth transmitter) the summer of 2020 and attached it to my road bike with the provided water bottle mount. I ride about 250 miles a week, rain or shine; usually alone, sometimes in a group. I've had occasion to use it 3 times in 4 months. The first and second time it worked like a champ. Easy connection to the presta stem and easy disengagement after reaching desired tire pressure -- as displayed on the iPhone app. I think the trick to getting a quick disengagement (and not loosing tire pressure) is to put some gradual pulling pressure on the nozzle chuck and then releasing the chuck locking lever. When I do this, I get a quick disengagement of the nozzle and loose very little air.The 3rd time I used the pump was on a group ride and this time the strokes were not as smooth. There was some friction there that was not present the first couple of times. The handle became very hot to the touch as I approached 60psi. This was not the case the first times I used it. Those earlier operations were smooth and pump handles never became warm all the way to 80psi. During this 3rd event when we got close to the 60psi mark the bluetooth connection dropped with the iPhone and failed to reconnect. That was OK. I knew each stroke was giving me 1/2 psi per stroke (pretty good for a micro pump). 40 seconds later we had 80psi.I wrote to Silca customer service to ask if I needed to perform some kind of maintenance on the pump. The same day I sent my email to Silca, I got a reply with a sincere apology, a promise to make this right and a request for my address, which I provided. They then informed me they would send a replacement pump out immediately. A week later I received my replacement pump. Now that's great customer service.Based on the way they stand behind their products, I plan to give their new chain lubrication products a try.

I originally gave this a poor review, but after a manufacturer exchange the replacement unit is working much better than the original. I used it today and the gauge app worked perfectly. The pump head I still find challenging to get on securely, it takes a bit of force.

Don't believe the hype. It has connected only once to the iGauge app, and briefly at that. Did not get a tire pressure reading in the brief connection. I now own an overpriced, overlarge regular hand pump. Contacting manufacturer regarding a replacement.
