Update
I bought one just like this a while back prior to buying this one. The previous one works great, but I wanted a spare. Unfortunately, this one that I bought in November 2025 has a very dim light and does not seem to hold a charge. I do not know if the quality has gone down or what, but I am very disappointed, because I love the 1st one I bought and was looking forward to having a spare. Upgraded to 5 stars (originally gave 1 star). I returned the above referenced one that didn't work. The company sent a replacement that I received within days and the replacement one works wonderfully just like the 1st one I bought. Kudos to this company!!!

The light only turns on when I press the button
I was really excited to use this wrist flashlight for my winter night dog walks, but it only worked once. After that, the light only turns on when I press the button and doesn’t stay on. Unfortunately, I no longer have the original box, so I can’t return it. Very disappointed.

Bright LIGHT to see with
I ordered them for someone else. She like the shiny light on your wrist. You can see in the dark.

Nice, but...
Works well, but for only about 5 hours before needing to be recharged, which takes quite a while.

Best Invention Ever!!
Love, love, love this! Comes in handy when walking my dog at night. I like not having to hold it - I strap it onto my wrist and go. The only complaint is that it only holds a charge for about two days.

Definite game-changer for safety.
My husband and I were looking for this exact item for our predawn walks with our dog. Summers are brutal where we live, so we are walking before the sun rises. When our dog does her business, we were searching through our backpacks for our flashlight. This wrist light solves the problem, it's already on! I use the red flashing mode when walking, my husband use the white light to light our path, as well as picking up after our dog. We put them on before we leave the house, very lightweight, and the Velcro band makes it super simple. I didn't want a product I'd have to buckle on my wrist like a watch. This is easy. They are now a permanent staple in our backpacks for walks and hiking trips.

Stopped working within 2 months
I bought this for the after dark/before dawn dog walks and it was great until it wasn't. Suddenly the light would just go out even when fully charged. Sometimes it came back on for a minute or so but would go off again.

Broke after a couple uses. Trash.
Broke after less then one charge cycle! Awesome concept. I would love to spend $80 on one with a nice G-Shock like band and a reliable Cree LED and quality electronics and a on off only switch and a separate mode/brightness control. (This is a very important feature. We do not want one button to control everything to save 15 cents on a 2nd button.)

Nice light. Not worth 25
