perfect in every way
This is the best and only twistlock you will ever need and the color is awesome. Replaced a couple of older ones and could not be happier with this one.

easy to handle
Old man with really bad hands,using this one handed, this carabiner is the easiest twist lock that I can find for my size hands and limited mobility. Keeps me on the rock

Best twist lock around
The RockLock has to be the best twist lock around. I was looking for a larger twist lock pear shape carabiner with a large gate opening to use on my cowtails for caving and this hit the mark. This is the largest opening I can find in a twist lock. Twist lock is super easy to open with thicker/muddy gloves on. Easier to clean/decon and durable. Larger opening makes these super easy to use at anchors, quick to clip safety lines, or to clip the ledge above your anchor knot. I also use these for making a top rope anchor as remember to screw the gate down, I’m bad with that, and it doesn’t take two hands to manipulate like a trilock. I can not recommend these more.

Twist lock review
Fantastic Carabiner!! My main use for these is on top rope solos as I don’t want to have to twist a screw gate. Very versatile piece of equipment!!

Color confusion
Nice easy action. Only wish the color of the screw was different so it’s easier to tell this and my screw lock apart

Buy once, cry once!
Yes, there are less expensive options, but these are worth the extra money. The auto lock feature works flawlessly, the the large, textured gate is easy to use even when wearing mittens or gloves. Purchased these to use in teaching Low Angle Rescue courses for the NSP.
