Sorry that your Thermacell repeller is not working. Have you checked to see if your device is heating or if the mat needs to be replaced? Mats should have a bit of blue color left/ A good indicator that your device is on and heating up is seeing the orange glow in the view window that can be found at the top of your repeller. If you are still having trouble, contact us directly and we will help you out.

Hi there! Thanks for the review. We are sorry that your Patio Shield Mosquito Repellent is not working to our quality standards, but we can hopefully help! We’ve got thousands of happy users to date, and have tested it extensively in extreme buggy conditions before we put our name on it. This product is fueled by butane which means it starts very much like a gas grill does. Turn the valve on, wait 5 seconds, then click “start”. It might take a few times like it takes a few times to get a grill going! You can always contact us at service@thermacell.net or 1-866-753-3837 with questions or concerns. There is a 100% Satisfaction Guarantee on all Thermacell products.

We apologize for your less than satisfactory experience with our product! We at Thermacell pride ourselves on our products and our ability to protect people against pesky mosquitoes. We stand by our products with a 100% satisfaction guarantee. Please contact us at customerservice@thermacell.net or 1-866-753-3837 so we can make things right for you
