Patio Shield

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.

As someone who spends a lot of time outdoors—whether it’s grilling on the back patio, camping with my family, or just relaxing with a good book—I’ve tried just about every mosquito solution on the market. Sprays, candles, zappers... you name it. Nothing has come close to the Thermacell 15 FT Mosquito Repellent. Instant Relief, No Mess Within minutes of activating the unit, I noticed a dramatic drop in mosquito activity. The 15-foot zone of protection is no exaggeration—it truly creates a bubble of comfort. No strong smells, no sticky residue, and best of all, no more itching. Sleek, Silent, and Portable The design is minimal and unobtrusive, making it easy to incorporate into any outdoor setup without it being an eyesore. It's also completely silent, which makes it perfect for evenings on the porch or quiet camping nights. I appreciate how compact and travel-friendly it is—great for tossing in a backpack or picnic basket. Effective and Hassle-Free It uses a fuel cartridge and repellent mats, which are easy to install and replace. I especially appreciate not having to constantly reapply sticky sprays or wear uncomfortable citronella bracelets. This device lets me enjoy the outdoors the way it was meant to be. Pro Tip: I keep one near our outdoor dining area and another by our kids' play space. It’s made our summer evenings so much more enjoyable. As someone who values quality, effectiveness, and smart design, I couldn’t recommend the Thermacell enough. It delivers exactly what it promises—and then some. I find myself reaching for it regularly, and it’s earned a permanent spot in our outdoor gear.

Id give this a 3.5 stars. 15 foot zone, no. I have the Thermacell sitting on a table in a 10x12 gazebo. With the claims that should easily keep away the mosquitos. I let it warm up and you can see the smoke coming out the top. I have seen several mosquitos fly by, even thru the smoke. Why I rated it so high is because the mosquitos seem to keep going. I do not have any new bites while I have been using the Thermacell, for about the last several days; we've had an uptick of mosquitos. I am normally within a couple feet from it but I dont doubt if I was farther from it I would be bitten. We don't get a lot of mosquitos so if your at a place that has a lot you may get less bites, if thats any consultation. Over everything else I've tried, other than spraying myself down the deet, the Thermocell has been the most effective. I will continue to use this. I enjoy my cool mornings and evenings, where im normally chased inside because of the mosquitos.

Used this for camping last weekend, I was impressed how well it worked . It was easy to set up! It did seem to take about an hour to reach its effectiveness , but we started off the evening with a few bites and ended with mosquitos no where around our area !

Have had these for years!! they are excellent at getting rid of mosquitoes works great!

It’s effective but the fuel did not last anywhere near the 12 hours the product claims. I can see it getting very expensive to be constantly buying refills so I will be looking for an alternative that actually lasts more than a few hours.

I can’t say enough good things about these. I have two for myself and bought others for friends and family. I’m super susceptible to getting bit by mosquitoes. They seem to pick me out from a mile away, and I have a big wall off ivy in my backyard that is a breeding ground for them. But I can sit out back for hours with this thing and not even get one bite!

¡Es un producto muy bueno que usamos en Canadá pero se rechazó la importación a México!

The unit needs to be stood on perfectly flat surface to allow air in the bottom (the base is shaped) or the flame will go out.
