I handwashed a bike jacket with the green keywell usb under water for 15 minutes and the rubber cap over the usb port not closed. After I shook the water out and it dried a day later, it worked perfectly. Keywell lights have a very long clip that is great for attaching to clothing or zip ties or the slots in bike bags.and they are super bright for being seen.My kong front bike light is good for one hour. I've used my red and green keywells for a five hour night ride and they don't dim at all…

UPDATE 11/18/18: Hats off to Keywell. They read my review and promptly reached out to me. They were professional and polite. Almost immediately, they offered to replace the faulty light AND DID! I received the light and got a follow up email the very same day! I was very impressed with their exemplory customer service. I have upgraded my review from 4 stars to 5 for the customer service, not the light {switch}. yet! I will see how it holds up (& update my review), which was my initial and ONLY…

These lights are great for my evening walks, which sometimes extend into the dark. It’s much more comfortable than the 90 degree days. All five modes are extremely bright. I once had a police officer turn on his overhead flashing lights as a kind of thank you and joke at the same time. lol I was using the flashing blue and red lights. Identical to his. I have tried other brands and these are by far the best. The clip is strong and will not snap off. I use the armband and it’s extremely bright…

This little light is perfect for running in the dark I clip it on the back of my hat and have it flashing so upcoming vehicles or people can see me in the dark. I love the fact that it’s rechargeable so you do not have to use batteries I highly recommend this for safety reasons

Clips could be stronger but OK. One of the lights fell off (and lost) off my dog stroller. Ordered two more but this time tethered it with some bell wire to help keep the lights from falling off in the future.

Buy this brand and this model safety LED's if you are looking for quality. I purchased similar looking models by other manufacturers on amazon. They looked exactly the same, but might have had 1 less led and used cr2032 batteries. The cheaper lights have clips that broke within a few days under nearly no pressure.This model is clearly high quality. The fact that it has 5 LED's and a rechargeable battery proves it is meant to last a while. Nothing is perfect, and weak plastic parts sometimes…

This is a very good lite to have when outside in the dark. The only drawback is that the clip to this device is rather flimsy and breaks. I have had to replace 2 x. Need to have a better clasp to adhere to clothing.
