How is the lock on this? Tight? Won’t come loose?

Contrary to the first answer, you will find a buyer posted a problem with the screw lock not remaining engaged. I also find that the the lip, which is covered by the screw lock, is too short; the screw lock was barely past 1 full rotation when it disengaged.The odd thing is that there is plenty of clearance to extend the lip further, for a more secure latch. I would say that this carabiner should not be relied on for climbing. Simpler uses should be fine. I have only one of these carabiners, so I could have a defective example.
