We live right next to a pond so we always get bugs galore during the spring and summer. We tried this outside over the weekend and saw a significant drop in the bugs where we had this repellent diffuser. It doesn't have a strong smell either which is nice because some of the repellent candles we've tried before just smell way too strong. This is a great little product and I love how we can take it wherever we go. Its easy to use and the directions are easy to understand. If you're trying to keep bugs away when you are outside this product is a great solution and I highly recommend it.

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!
