It locks up when you least expect it. I had done one up through my shoes (God knows why I decided to) and it wouldn't open. 10 strikes with a hatchet later, I broke it open. The screw gate had never shown signs of wear or grime deep inside the locking mechanism, but one day it decided to lock up. I didn't jump straight to a hatchet, mind you. I used a wrench, then channel locks, then I threw it on a vise and slammed it with a mallet–no good. I shouldn't even have to expend that much energy to open a carabiner. God forbid I was up on a wall when this happened...
Would not recommend. Used less than 10 times and the locking mechanism jammed (and will not open). Fortunately I was able to untie my master point and retrieve my static rope. Had this been used in any number of other climbing circumstances, the results could have been much more extreme. Do not buy.
no need to do a manual check to see if your locking carabiner is actually locked.
I used this for several weeks then I brought it backpacking to hold my water shoes in a non-sandy area. After two days of carrying shoes the locking mechanism was jamming. By the third day it was completely jammed and I could not open it. I would not recommend this due to the possibility of not being able to open it. (I'm a pretty strong dude too).
Easy to unscrew even with gloves on, as well as the perfect shape for extra gear.
I use it for the Grigri or Petzl belay/rappel devices. Works great.
Locks securely and tightly, lightweight and practical
it closes and locks like it should. No complaints.
