Works within an approximate 5' perimeter. We keep it on the patio table while we sit in the backyard.

I was a little skeptical at first but it. Really works! We can spend more time outside and not let the mosquitoes chase us inside.

I purchased this, the MR450 and 120 hour refill package. Can't get either one to ignite and the distributor will not let me return them.

Did not seem to do any good at keeping mosquitoes away. The butane takes are supposed to last for 12 hours but only last 4 hours.

So happy I bought this product. Works as stated, I have used it at night and in the early morning have not had any mosquitoes at either time.

I was skeptical about how well these units work but this unit is so AWESOME I will buy another for my brothers house!

I’ve been using this product for quiet awhile and it helps a lot! In the Deep South you have to have it!

Overall, I think this is a good product. It seemed to do the job. I just wish refills weren't as expensive.

I have been using this for years. It’s the best thing I have ever used. I tell everybody about than.

I have used this for the last 3 summers, hoping that it would work. I still have to fight off mosquitos.
