Black Diamond Magnetron RockLock Carabiners.
The Black Diamond Magnetron RockLock Carabiners are an essential safety component for any climbing or rappelling enthusiast. With its trademark Magnetron technology, the gate of the carabiner uses two magnetic arms, with a steel insert in the key lock nose, to hold the load securely and to maintain an interference-free closure. This helps prevent rope snags, for added safety. It is operable with either hand, making it an essential item to have in an emergency, when both your hands may not be free. Designed with a curved spine, its gate opening is maximized to keep you securely in place, while providing the necessary balance. The original RockLock shape makes this carabiner ideal for belaying. The Black Diamond Magnetron RockLock Carabiner is a must-have addition to your climbing gear.

The Black Diamond Magnetron RockLock carabiner uses a truly revolutionary gate that locks shut with magnetic tabs instead of a traditional screw gate. The advantages? Nothing to freeze shut in the winter or to clog up with sand, and you can operate the gate with one hand. Not to mention that this gate is significantly faster to open then traditional locking mechanisms. To top it all off, Black Diamond gave the RockLock carabiner a keylock nose that won't snag on gear, slings, or bolts when you tear down your anchor to head up the next pitch.
The Black Diamond Magnetron RockLock locking carabiner uses the power of magnets to give you the security of a locking 'biner with incredible ease of use.

I bought two of these to use canyoneering with my wife as an alternative to screw gates (which can jam up sometimes). We absolutely loved them on the first 3 trips, no problems whatsoever. They work much like an auto locking biner but for some reason are so much more fun to play with (even when not rappelling).
That having been said, on the last two trips I did, both my wife and I had issues with them jamming with sand to the point they either wouldn't open or wouldn't close. Her's especially became ridiculously jammed and even after washing it through clean-ish water vigorously and banging the crap out of it, we couldn't get it to reopen until the very end of the canyon (good thing I always have backups).
If you're not going to be using these for canyoneering or around much sand/grit, then they should work perfectly. But for me and my house, we will still have to buy screw gates.
The concept of the auto-locking mechanism using magnets is a stroke of genius. Super simple and great for one-handed operation. I used it on the end of my rescue sling during swiftwater rescue this summer . My one gripe with this carabiner is the way the mechanism is set up the slightest bit of sand and the gate won't open, not the best for rescue situations. I've also had reports of people using it when ice climbing and a similar problem occurring. Great for a belay biner but I'd discourage any situation where the biner would be on the floor making it more susceptible to having the mechanism be clogged.
