Grivel Mega Twistlock HMS

When the Grivel Mega Twistlock HMS arrived, I was surprised by the lightness of it. So far, it has performed as I need it. I use it to quickly set up ground anchors for groups and for personal safety at abseill stations. My only gripe is that the twistlock doesn’t feel as robust as the rest of it. All in all, very happy and will probably buy some more for the same purpose.

Not impressed

It works and does what it should, but I just don't like the mechanisum: to open the gate you have to lift the collar. I have others where you don't have to, which makes this feel more "blocky", not as smooth in operation as it should be.

Big HMS

It's very big carabiner, easier to use for people with bigger hands. The quick lock mechanism is simple to use. The width of the krab is quite wide to its reduces friction when belaying.
