Repel Realm Zone Mosquito Repellent Device + 1 Refill Cartridge (40 Hour)

I think these units are a better value than it's competitor due to its long battery life. Where the competitor craps out in a few hours this unit lasts many more hours of use. The system works pretty well, I use a combination of repellents together but I can see the wall of mosquitoes trying to get close but won't. Yes, the aggressive ones still force their way in but it works on the majority of mosquitoes.

I am not easily impressed and skeptical by nature. This Repel Realm Zone works to prevent 90-95% of the mosquitoes pokes I had been been experiencing. I estimate a 6'-8' effective zone. Generic replacement bottles don't necessarily fit, but you can refill the original bottle with little effort. However, generic was slightly less preventative. I love sitting outside in the evenings, but hate smelling like repellent. This stuff is odorless. It made my outdoor summer evenings enjoyable again!
