"I use them for everything...they are awesome!"
I have never had an issue with these. I love that fact that they are wire gate, which doesn't mean much to most people until you take a solid gate and smack the back of it against your hand. The noise...that is the gate opening. Scary...I know. I have heard several arguments about how they won't ever do that when you are climbing a wall and I believe them just about as much as...well anyways. These carabiners are light, strong, and very reliable. Not to mention they make great key ring carabiners, hammock carabiners, water carabiners, and things to mess with while you are playing at your computer or watching tv. So, with that, if you think you need one then buy two, if you think you need three then buy six, if you think you need one hundred then reevaluate whatever the heck you are doing!
This is a no frills biner but it does exactly what it is supposed to. You can't go wrong for the price. Very light weight and the gate is strong. It doesn't bounce when you hit the spine like bent gates do.
Im not a climber, but I appreciate a quality biner to attach to my packs for any reason I might need it. Snaps closed confidently, and is not expensive compared to lower quality ones that are only a few dollars less.
