Strange little thing

I guess you could keep this on your keys or something but I keep 1 in my first aid kit and clip 1 to my dogs collar. Really use your imagination. Where could you maybe want to clip a moderately bright light?

works fine enough, but have had a few times when turning it on it opens the battery compartment and dumps the batteries out. Then I have to find them with my cell phone light. Kinda defeats the purpose.

Handy and effective- please make a rechargeable version

The batteries only last so long so recharge would be quite nice. Great tool for moments where illumination is needed!

Pretty cool little light

Got it to attach to dog leash. It works great with an awesome design that you can work with gloves on.

Ion Keychain Light

This is a great product. I bought 10 of them for stocking stuffers and small gifts. Everyone liked them. One of them did not work. I call Black Diamond and received a replacement in a few days. Ralph Feeney

Ion Keychain Light Review by Philip

I purchased this for the first time ever because I thought it would be handy and hoped the light would be decent for the size. It's exceeded my expectations! Small and very portable, but the perfect design where I know I won't lose it and it's easy to use. The light is very impressive!

plus minus

great build quality. problem is batteries. very expensive design using coin batteries has relegated this to backup in my fannypack.

Great little light

I have this on my climbing pack just in case I need a light. Super bright for its size, I think the orange makes the light brighter.
