MENGZF Ultrasonic Mosquito Repellent Bracelets, Electronic Anti-Mosquito Wristband Watch with USB Charging/Waterproof/Reusable/Portable, for Children and Adults (Upgraded Version) (White)

I bought this for my daughter who has problems with bites. It worked very well. The only problem, the strap fasten wasn’t very secure and came undone several times.

The fastener on the strap is not strong enough to keep the strap fastened so watch drops off easily - I lost my watch and my husband lost the little black fastener do held together with wire now. Shame about strap issues as watch works well and looks good

The watch and strap are absolutely atrocious. It is a standard digital watch, so it's not a great technological challenge for the company to get right. However, within the space of a few hours it can lose or gain anywhere between 2 or 20 hours in time and lot of random minutes. So its definitely not a question of it getting leaned on and accidentally going up or down an hour. E. G. Despite having reset the clock in the late morning, I notice the time is wildly off at 3.10pm, saying 7.56am, so I reset it to 3.10pm. Half an hour later it says 23.07pm or 4.53am or some other random time. It's bonkers, entirely unreliable and it keeps on falling off the strap. I kept it in case the mosquito repellent actually worked, BUT IT ABSOLUTELY DOES NOT. I made sure I had it turned on to full power before going out and still got bitten lots. I wish I could get my money back, but by the time I had gone abroad and tried it the refund window was closed. Absolutely does NOT do what it says at all. AVOID AVOID AVOID. Do not buy !

Didn't expect much, and how can an assessment be made when you have nothing to compare? I have used this a few times in the open and so far no gnat bites. But does this mean they have been scared off or just not there anyway?All the time I dont get a bite I will carry on using it. Despite it having a clock function I never managed to set it. But I guess that is par for the country of origin. Anyway I bought it for the gnats not the time and so far that area of functionality seems like it works.

Doesn’t work!

Mosquito control but the band pops open so I use elastic band to keep on but seems tokeep mosquitoes bites at bay

I can't work out how to get the time correct as no instruction leaflet included. Not had a bite since wearing but had 9 in 2 weeks previously

This has the most terrible strap, which does not fasten in a sensible way. Therefore it continually falls off. It is the poorest. tackiest strap ever. The problem is that the watch itself fits into the strap, so you cannot even buy a new strap for it. It is a complete waste of money. And I bought 2, one each.......40 wasted. Please don't you waste your money too.
