Thermacell Mosquito Repeller Patio Shield; Includes 12-Hour Refill; Highly Effective Mosquito Repellent for Patio; Bug Spray Alternative; Scent Free; No Candles or Flames

I have several of these units and can't say enough about how well they keep mosquitoes and gnats away. I do use 2 units for my 20 x 12 foot deck. Manufacturers always tend to over exaggerate the effective range on products like this. I use the half rule. If it says 15ft range I assume its going to be 7 maybe 9 feet which is why I use two units at the same time. If the bugs are really bad I sometimes add a 3rd unit but they do keep the bugs away. It's important to realize that you should turn these on and place them outside at least 15 minutes before you enter the area. This is actually what the Manufacturer suggests anyway. They do take time to heat up and for the vapor to start coming out of the units and to spread around the sitting area. As for the blue pads, I hear some complaints they turn white in less than 4 hours. Turning white doesnt mean its not working. The oil is still being emitted even when it turns completely white. In fact just having them in the sun and humidity will make them turn white but it still takes about 4 hours to exhaust the pad. One other thing to note is once you open the package the clock starts ticking. If you used it on day one for 2 hours and then don't use it for a couple days they will have dried out and no longer work and a new pad needs to be inserted. With that said its not the greatest if you just plan to sit out for an hour but they are still the best solution I have found. I ordered the rechargeable unit that uses a liquid cartridge instead of the pads to see if these are better for shorter usage times. I'll update this review once I try it. Update on Rechargeable version with the liquid cartridges... This is the way to go! Theybwork just as good as the butane models with the pads. They actually heat up faster too. When I'm done with them I turn them off and they are good to go even days later since the liquid doesn't evaporate from the wick. No pads pads or butane cartritges to deal with. When repellent cartridge is empty just drop a new one in. Couldnt be simpler. Note! The cartridge that comes with the unit is only partially filled, just like when you buy a new printer. The replacements are completely filled.

We live on mangrove water in Florida and have tons of no-see-ums, pretty much year-round since we don't get cold winters any more. We've used Thermacells for years so that we can actually sit on our dock or in our yard without getting eaten alive. They work perfectly when used properly. We set them outside near our chairs 10-15 minutes before going out. We usually use 2 of them spread several feet apart, and the no-see-ums stay away. You have to make sure the blue pad still has some blue on it, or the scent won't be strong enough to keep them away. These babies are a quality of life changer!

So, I live in the South and during the summers, it gets hot, humid, and mosquito-ridden. During these times, I like to stay inside as I may be the biggest mosquito magnet there is. It doesn't help that I have allergic reactions to them, so win all around for mosquitos. I have used many different mosquito repellants separately and in combination with others. I will say that this is pretty good and one of the best. It does a good job of repelling mosquitos in a certain radius (not so sure if it's as big as advertised, but it is big enough). I like to set it out when I'm with family on the porch, but I have to make sure that I set it out in advance and still use other repellants (long sleeves/pants and spray). Even with all these preventative measures, I still get bitten but it does feel like a lot less. Buy to use for camping or eating outside in one area. However, it does not work well if you intend to keep on you and walk around. It's a bit larger than a soda can (more like a small thermos) but it is portable.

The Fuel-ZoneGuard is prefect for camping when you don't have the ability to charge a battery. The fuel canister last 12 hours and mosquito repellant pads last 4 hours. Thermacell also makes 12 hour pads too. Replacing the fuel canister is quick and easy just turn off the unit and unscrew the canister from the base. The unit will last a long time since its a mechanical system. Run time will also be constant since it runs on fuel. All in all a great item for rustic camping adventures.
