Buying you first repellent insert immediately double your cost of the device system. Take care to not put in too far in advance if need or forget to turn off and mistakenly run it dry.

It's ok. Cartridges leak so there is definitely no chance of getting your moneys worth. Coverage zone is much smaller than advertised. Maybe the other stuff they sell works better, I don't know.

The device only lasted one summer season. I’ve had to buy new devices each year which is costly so while they work well regarding mosquitoes, the device quality and durability is disappointing.

This product works well....provides us a mosquito-free zone on our 25X15 deck as long when the wind is still... the breeze usually enough to keep them away otherwise...overall, very nice.

My daughter (a mosquito magnet) cannot visit me for outdoor meals unless the mosquitoes are under control. The Radius is the first device that has made this possible.

Very difficult to judge whether this product works. If there is the slightest breeze, the mosquitoes are plentiful and don’t seem to be bothered by it.

Really helps when we are out on our patio. Works best when its on the ground between us (on a table seems to leave and area "untreated" and we get some mosquitos)

These liquid repeller units are very long lasting and work amazingly well! Hardly got any mosquito bites after a week of camping in New Hampshire in the summer time.

Garden weeding is not my favorite job, it seems all manner of biting bugs want to help! Thanks to Radius repellent refills it was at least a deterrent saving me from hours of itchy skin.

This product works great and is so silent in the background. It’s nice to be bug free for once. The only downside is that it takes a very long time to charge!
