Query: Dont get this!

I got this item only because it's supposed to be a quick detach riser, but it's not. On the box it says that it is as well, but theres no way you can detach it in less than 60 seconds. For the money that I spent, I could have bought 2 of the regular raisers and been more pleased than what what I am with this piece of garbage!
