Review on RISEMART Mini LED Keychain Flashlight - Pack of 10 Black, Ultra Bright Key Ring Tiny Light Torch with Batteries Included by Cory Spence

The description says it contains two batteries. I doubt it. Shines a lot brighter than any of my previous purchases. I didn't have to wait a month for a package from China. All ten lamps worked stably. The always-on switch worked with all ten without any problems. No idea about the battery life as I just got it today. There is no rotating bracket on the keychain so they can get tangled up with your keys. One star for that. Otherwise very good, I only make ten more packs.
