Hi there! Thanks for the review. We are sorry that your MR300 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. 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. Before reaching out, could we ask you to try a few things? • Please be sure to properly insert the fuel cartridge and replace it approximate every 12 hours. Also, you should replace the insect repellent mats approximately every 4 hours (it will turn white on the top side). • To ensure the unit is working properly, please be sure that there is an orange light glowing in the view hole (… on the top of the repeller or on the brim of the lantern) • 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!
