relaxing with no bites
Bought this yesterday, brought it home set it up on the patio. Went out before my wife and started it up. We enjoyed a relaxing evening, with no bites. If this is any indication on how well it works we will be more than satisfied.
Love this product!
We live in Moncton NB. So many mosquitos that you can’t enjoy your outdoor space. Bought this last year. Absolutely effective! Love it!
Bill
I've been using these for years, they work! Buying refills today in advance of a trip to the Florida Keys...you need Theracell down there for sure!
Works great.
Great product. Have used for years both hunting/fishing and at home. Works great, we live in Louisiana-we have mosquitoes. This keeps them at bay so we can enjoy the outdoors.
Very Effective
After trying everything from tiki torches to citronella candles to mosquito coils, this is the first product that truly seems to keep mosquitoes at bay. The cartridges are easy to plug in and the lamp-shaped diffuser is easy on the eyes. I just wish the pads lasted longer than 3 hours, though the change in color is a simple reminder of when it's time for a new one. I'm very pleased my wife found this product!
works great at keeping mosquitoes away!
works great better than commercial service we have been using, would highly recommend for home or business.
Happy
Very happy with the mosquito free environment created.
Thermacell
It works!! So glad we tried it. Thank you Kevin for recommending Thermacell
Wow!
It really works! Safe around my pets and the hummingbirds.
Two Words... IT WORKS!
I have used Thermacell for years and it works. I live near woods and my personal unit i clip in my belt allows me to enjoy my back yard.
50/50
The two “pads” I have used so far are not lasting 4 hours. They are turning white in less than two hours. I thought I ready they should last 4 hours. Maybe I got duds. I don’t know. The first one I used worked great.
Excellent product
Purchase 1 then another last year and my son bought 2 more and I gave him one for a gift so I think that shows we'd love it would be great if we could get a little better deal on the refills
Excellent
excellent easy to use repellent. Creates a great barrier between you and the nasty biters!
WORKS!!!
I would never have believed how effective these are at expelling bugs and mosquitoes from an area AND keeps them at bay!!!
I love my ThermaCELL
I have had my ThermaCELL for about five years. It works great! This refill kit was a great price and will last me through the summer.
Surprise! It works!
I was doubtful when I bought this, and was fully prepared to return it if it didn't work. I'm pleased to say that it functions quite well - the mosquitoes are thick this year & since I've been using this, they stay away.
helps combat pesky biting bugs
We have several, and enjoy using them when we are outside at dusk/night. We take them camping or to the beach
Works Wonderfully!
Living in Florida, this is absolutely necessary year round. We can sit on the patio for 4 hours without getting mosquito bites! I've been buying this for 3 years based on recommendations from hunting friends who use it in their blinds and will continue to buy this.
Could not hunt without!!!
I have been using Thermacells since they first came on the market when they were "As Seen On TV". Especially this year with it being so hot in the south Im still using mine today. Dec 22
the system works great
one nite in a very bug rich environment two of us sat the unit on a table between us and for 4 hours no bites. great system
GREAT!!!!
I was told about this from another shopper at Wal-Mart about a year ago. He swore by it and, now, I do too. Will never be without it. Use on patio during the spring and summer in NC and FL.
Best ever
One whiff from the Mosquitos and they turn around and go the other way.
LOVE!
This is the best thing since sliced bread! I tell all of my family and friends about this product and encourage everyone to buy one or more.
Effective!!!
I purchased my ThermaCELL last year, but never had the chance to use it until this week. My son-in-law recommended it because it uses his for hunting. We've had heavy rain and mosquitoes are crazy thick outside. We were able to sit out on the patio for hours every evening and the mosquitoes came nowhere near the patio while we had the ThermaCELL on. This thing is effective and fantastic! Thank you ThermaCELL!!!
Love my thermacell
Great products thermacell. They actually work, and now I don't have to use DEET on myself and my son. I am so happy I heard about this from my friend.
Amazing product!
Love love love this product!!! Definitely makes outdoor fun less bothersome!
