OFF! Mosquito Lamp I protects you from mosquitoes for up to 6 hours. Enjoy an outdoor occasion with friends without worrying about pesky, biting mosquitoes. Simply by lighting the candle, the lamp releases an airborne repellent that covers an area of 10 ft x 10 ft (100 sq ft.) Product label may vary.
I recommend having 2 to cover a deck space, but happy with the purchase. We have a decent-sized deck, started with one and it worked alright, but no bugs around when we upgraded to 2 The refill is a little tricky at first, but you just have to get it down. If you typically get bit like I do, I'd invest in these.
Have only used it once, so far so good. Light smell.
