They seem to work. We're not in the thick of mosquito season yet but mosquitoes love me and so far they haven't been quite as bad wearing these bands.

I originally bought these for a trip to Maui and I didn't get bitten, but my husband did (who did not wear one). By the second day, he gave up, and he put one of the pink bracelets on. The rest of the trip, both of us were mosquito bite free. I also rent out travel trailers on outdoorsy. I include them as one of my included amenities. My recent renters used them when they camped in Fort Stevens, OR (notorious for mosquitos) and they gave feedback that they didn't get new mosquito bites AFTER they started wearing the bracelets. I usually just wear one, but if I feel there is an excessive amount of mosquitos, I'll wear two--one on my wrist and one on my ankle. Love these things and I am reordering

I like these for sporting events and other places where it is awkward to bring in a full thing of bug spray. Im always the friend that gets bitten. I wear on or two of these bracelets and I am fine.

So we work in the out doors all summer long. I live by these. For those with kids who fight like hell to put bug spray on or hate the taste like most people then these I highly suggest they come quickly, they come wrapped separate! For the price and amount you get in this deal it was worth the what $10. Deffff try these if you haven’t I even wear them on top of bug spray.

Easy for kids and adults. No more nasty spray. No whining or complaining.

10 days in Jamaica in August, one mosquito bite. Math don’t lie. These things work, way better than sticky stinky spray, and mosquitoes LOVE me.

I use them because we have mosquitoes and fleas in the courtyard of our building, these insects use me as a walking blood buffet… I use these… I do have to double them up but they work great and a good long time … I’m very happy with them… no bug bites I’ve got the neighbors ordering this product too …

If you can see in the picture, we had them around our wrists and ankles in Costa Rica lol. No issues with mosquitos at all. We did pair them with wearing lavender oil as well. Definitely a good buy for tropical places
