Thermacell Mosquito Repellent Rechargeable Adventure EX-Series EX90; Patio Shield with 9-Hour Battery, Includes 12-Hour Refill, Rubber Armor & Carabiner; Scent Free Bug Spray Alternative

It states that a 12 hour refill is included but unfortunately it wasn’t.

The product worked from the point of view no bites in the 2 hours sat outside but the capsule it came with had barely any liquid and looked like it had leaked and now NO REFILLS on Amazon and massively expensive refills off another site so be warned it works but Will be Expensive to Run if you can get refills.

Does it work? Short answer: Yes. Long answer: I live in Florida. We have some swamp areas on our land. I've been hurting close to that swamp. We've been in a drought for a couple years now and the swamp has been dry until recently when we've been getting lots of rain. Now that the land is wet again the mosquitoes have been awful. It's been unbearable to sit in the stand with all the mosquitoes and I would end up leaving because it was so bad. I'd cover my head with mosquito net and wear long clothes and gloves but I'd still receive hundreds of bites through my clothes. Just sitting there I could see a cloud of mosquitoes around my head with the sound of buzzing almost deafening. It's bad! So I purchased this thing sceptical that it would work just because of the extreme volume of mosquitoes in the area. It rained yesterday. I went out this morning with this device and turned it on. I placed it close to me and wait to be attached by the hoard I know is looking for a meal. And, nothing. I'm sitting in the dark with a red light on and can see them close but not coming too close. I can hear some buzzing in the air near me. And as time passes, there are fewer and fewer. Every once in a while one or two would come in close, I'm guessing as a desperate attempt for blood. They don't stay long. When there is a gust of wind, they seem to get the opportunity to get closer. Over 5hrs, I took 3 bites as compared to being without the thermacell, you wouldn't be able to tell where one bite ended and the next began. And that would be through my long sleeves. The EX90 proved it's worth to me within 10 min and throughout my 5hr sit. As far as the deer are concerned, I have deer on camera less than 40yards from me and the wind was in my favor. It was just too dark for me to see them and get a shot. So, I can't say yet wether or not it bothers the deer but there's no way I will go out there again without this thing if the mosquitoes are active. What I don't like: The lights are bright so I cover them with a piece of tape. And there is a loud activation and deactivation sound. It does take a long time to charge. So make sure you get it charged well before you intend to use it. Other than that, it works great for repelling mosquitoes.

An absolute gamechanger. My partner uses this all the time in our backyard and shed. We love that it's usb rechargeable! Shoutout to 'Camping with Steve' on Youtube. he uses this brand for all of his adventures and is the reason we decided to get one too.

The promise: an electronic device that you can turn on to keep mosquitos away. The electronic part is a partial truth, as the electricity is just used as a source of heat, but it's an effective way of keeping mosquitos away. Thermacell devices, electronic or not, work by slowly releasing allethrin, an insect repellent. Low heat is used to make the repellent go into the air. Allethrin is mostly harmless to humans and pets, though it's recommended that you not ingest the repellent or use it near food. There is nearly no smell; the repellent itself is odorless, but the device sometimes releases a bit of smoke. The older fuel-based ones, which either use butane fuel or sit on top of an isobutane fuel canister, use felt mats to hold the repellent; you have to replace the mat after four hours of use. The electronic ones instead use a cartridge loaded with liquid repellent and a wick that slowly releases it; it can provide up to 40 hours of use from a single cartridge. The electric power is simply used to provide heat. Thermacell makes two versions of the electronic device. The more basic one has 6 hours of battery life. This is the upgraded one with a battery that lasts 9 hours, which is enough to keep the device powered for most day events. If you need more run time you can connect it to a USB power bank, or to an AC-powered charger if you're in a location where outlets are available. The cartridges are good for 12 or 40 hours of operation; the bigger ones will cover an entire weekend of camping if you connect it to a large enough power bank to keep it running that long. You have to supply your own charger; the Thermacell does not include one. The company says it will keep a 20 foot area clear. That's true on a reasonably calm day. Winds will carry the repellent away so the effective range is smaller on a windy day. If the winds are REALLY high you won't need to run it because the mosquitos won't be flying. Make sure not to lose or throw away the cap of the repellent cartridge unless you are certain you will use up the rest of its capacity in the current use session. You need to put it back on before you store the cartridge. I recommend keeping the cartridges, new or partially used, in a Zip-Loc bag to make sure you don't end up getting the repellent on other things; the cap is supposed to be enough, but belt and suspenders :)

This is great, Mozzies and midgies totally gone. Keep the little cap thay screws onto the liquid cartridge as it wilo evaporate when not in use. Otherwise completely excellent, even when its windy.

Have used in patio situation, enclosed 3 side & a roof with zero wind, still getting mozzies after 1, 2 & 3 + hours after starting it more than once
