Thermacell MR300 Mosquito & Midge Protector; Includes 3 x 4hr Mats & 1 x 12hr Cartridge; Easy to Use, Highly Effective; DEET-Free; No Spray; 20 sq m Zone of Protection - Graphite

This does keep the midges away.

Purchased this product as I used to have one in Australia and they work well. The cartridges aren’t cheap to replace but if you remember to turn off the machine they will last 2/3 evenings. They do keep the mosquitos away once it warm up. Certainly worth buying so you can enjoy being outside in the evening.

Excellent

Best of the best! Value for money! Was our life saver from moscitos. Awesome !

If you are travelling to the west coast of Scotland, I’d give this contraption a miss. Was pretty useless against the midgies!

This is a great tool to keep the insects away from my tent or Tarp setup while Camping , each pad lasts about four hours , and you can heat four of them from one gas cartridge, I recommend this highly if you go Camping

Totally ineffective against UK biting midges makes no difference at all regardless of positioning/wind direction/speed/duration. Complete waste of money

Its does work I seem not to be getting bitten as much, not very good on a windy day. I find I get three morning session per gas canister and one session per blue burn pad. I've given it 4 stars as I am still not convinced it will do the job when there are a load of mozzi's by the water. But as said not been bitten yet. Shall see what happens in the summer when by a lake.
