    Why change if not broke2025-08-30
    Doesn’t work like the original
    I have been a long time Thermacell supporter, but I have bought four of the 300 series for hunting I have a lot of the others I’ve never had a problem all four of these 300s I cannot keep running. They will fire up for a quarter second and then go out too many times they’ve left me stranded in the south Florida mosquito woods, swatting mosquitoes cussing a brand new thermacell not sure what the difference is. I have used multiple different cartridges for propane to make sure it’s new and fresh with no difference. i’m not buying another 300 series that is for sure.

    Pads became worse
    I agree with other reviewers that te pads have changed. They turn white after an hour. Not after 4 hours. Please Therrmacell react to this. What has happened? Isn't it a problem that they turn white so soon. Will they still work? Have they changed? What is going on? The refills already cost a fortune and now they work just 1 hour. It is the only device that works! But normally people cannot afford it anymore like this.

    This thermacell, is not even a year old ,and it has quit working I have one of the first generation and it’s still going strong.seems like these new ones are junk. And of course unfortunately I don’t have the receipt anymore. I have recommended thermacell in the past to people but if they keep building junk like this I don’t think I’m going to anymore.
