Its is big
Agree with the other reviewer. This biner is a bit large but it is my go to for everything and anything. I use it to belay with both a standard atc, mammut smart, grigri and it works great. I have both the twist lock and the locking and they are both great.

Great biner but large size
Buying this product I had intent for it to be used for a belay device. When I received the Rocklock I was taken aback by its size. I tried to use it as a biner for a belay device and just could not get over the size, it just got in the way for me. So I have now switched it to my anchor lock in biner and it works great. I recommended this product just know what size you are getting into. Well done Altrec as usual for offering such great products!
