The build quality, fit and finish of this keychain is below par. The key rings don't slide very smoothly, but it does get the job done in terms of being able to quickly attach and remove the various keyrings. One major gripe I have is that after using the keychain for a couple of days the battery cover for the light came off...I don't know how because the keychain simply went in and out of my pocket several times a day (this is what I call 'normal use'). The battery cover connects the 2 batteries for the light to function, so now that there is no battery cover, the light is inoperable. So at the end of the day, this thing does hold my keys, but I wouldn't buy another one.
