Great flashlight

This is a great flashlight! It hangs on my purse so it’s readily available. I really like the fact that I can recharge this whenever it runs low. Also, this is the brightest little flashlight I have seen.

Small but mighty

My wife and I use this light daily. It's small enough to work for darn near anything.

Perfect Size

Great size for pairing up with your key fob. Just bought two for gifts. Free engraving was very nice
