Great little mosquito repellent!
Color: Black 1 Devices 2 Refills
I’ve been using this device on my patio and it actually makes a noticeable difference. It’s compact, easy to carry around, and I like that it’s rechargeable. The coverage is decent for small outdoor areas, and the refills are simple to swap out. Perfect for camping or relaxing outside without constantly swatting bugs. Definitely worth it for the price!

The product doesn't work.
Color: Black 1 Devices 2 Refills, Color: Black 1 Devices 2 Refills
This product is completely useless. I turned it on, and flies swarmed all around it—even landing right on top of it. It's false advertising. Don't buy it.
