MTKMQR-PR KeyMod Tool Free Quick Release Picatinny Rail 60mm

This qd pic rail is a great idea in concept but it's implementation is cheap and poorly thought out.. or I got a lemon.The whole thing is solid metal with metal attachment points but the small tabs you squeeze on to release it are frail loose wobbly plastic. I feel like I'm going to break it at any second.. the people selling it also don't have a clue about it because I asked a very simple question, how many keymod slots does it take up? They responded with not knowing what I was talking about AND they gave the wrong answer. It takes up 3 keymod slots, not 4.If this rail wasn't such a game changer on my Maxim 9, I would return it. However, I carry my Maxim 9 on a holster and being able to quickly attach and detach a light on the nightstand for home defense is clutch.These people should make the tabs metal for longevity.
