Easy to use in difficult situations
I have many of these and have been using them for years on the river. When time is a concern these little guys are your best friend! No more wondering if you remembered to lock them just pinch and clip and the anchor is set and the rescue is on. I don’t use these for rock climbing however I bet the best use would be for belaying.

Solid Carabiner - Except in Snow
I used a couple Magnetron Carabiners throughout the summer for multi-pitch trad/sport routes and basic mountaineering. Found them light and easy to manipulate. Winter has come to the mountains, and I find that these lock up when they freeze or pack with snow. To free them up takes a lot of effort; a whole lot more than with a traditional auto-lock - especially with gloves on. Just a Heads Up. Keep it from Freezing and it's a great carabiner. Kudos to Black Diamond for the inovative approach.

Favorite biner for PAS
This is hands down my favorite carabiner to use with my personal anchoring system. Doesn't matter if I am setting up for a rappel in a new canyon or cleaning anchors, I love the single hand operation with the confidence of a locking carabiner.

Love it! Makes clipping in so easy.
Got this over a year ago and have fallen in love with it. The double ping release makes it very easy to unlock and clip in. Checking the lock is simple. Bought the same one for my girlfriend! We both love it. Really durable as well. Won’t need another one for years to come.
