A bit misleading... - VISM M-LOK Folding Vertical Grip

It's a really nice grip, but it does not lock into a 45 degree position as stated, it says right on the package it locks into 90 and 180, you can set it to 45 and it kinda just stays there, it's tight enough to hopefully hold good, but it does not lock at a 45. Also, it says rubberized grip "pattern" I was under the impression there would be some rubber on it but there is not, it is all plastic, except for the little plug at the bottom which stores the allen wrench, which is nice, but still, i was really hoping for some rubber and a lock into 45 position, still a nice grip though, unfortunate.
