I purchased the MR300 two weeks ago and it's worked great for me! I set it up 15 minutes before my company arrived and we were able to enjoy the night festivities. Will purchase another one for more coverage area.
I hunt and hike in Northern Minnesota. We fight mosquitos, sand flys, deer flys, horse flies and no-see-ums. This product kills them all. Do yourself a huge favor and buy one. you will not be disapointed, you have my word on that.
Bought one several years ago and velcroed it to the dash of my side by side. It provides excellent protection in semi enlosed cab of windshield and roof. Just bought 2nd one for backup.
I am a huge Thermacell fan. They make by far the best mosquito repeller. I own two portable mosquito repeller and two patio lanterns and they work wonderfully.
