Bright for the size. - The KF03 build quality is great. Small size and light weight. Smooth turning action. Very bright for the size. I believe at this size this is the best keychain light on the market. I wish these were USB-C rechargeable and had two brightness settings but you won't find that on a light this small as of the writing of this review. I also have a KF00 which is the smaller, less-bright version of the KF03. The first KF00 I received was faulty and I could only get it to flash on about a quarter second at a time if I turned it just right but the replacement worked fine. Acceptable failure in my opinion since I've now purchased about 10 different products from this company and this was the only defect.

Bright for the size. *by L***P on September 18, 2023* The KF03 build quality is great. Small size and light weight. Smooth turning action. Very bright for the size.
