So glad that this biner is back. I love using it for belaying and rapping because it is less bulky than a traditional twistlock carabiner, and is even a hair lighter than the Triple Lock. You can really tell the difference when you need to spin in around (like when belaying from the shelf of an anchor) and do not need to deal with the fat locking mechanism on the gate getting stuck. Pick one up!
Everyone who had the old one raved about it, and I love it too
I was a little uncertain about the Magnetron at first because it seemed TOO easy to be truly safe. However, after MANY attempts to open the gate "accidentally" with no success, this has become my absolutely new favorite carabiner. It's easy to use and visually stunning. Almost everyone who sees me with it has asked to play with it.
I’ve waited 2 weeks for you all to ship this out. I spoke with a rep earlier this week and was told it was on back order until Sept 1 (which I said was fine and I could wait) and just now I get an email saying my order is cancelled! Meanwhile your site still says “in-stock” and “add to cart”.
You canceled my order after a month, then emailed me to tell me I should order soon some it was low inventory. And when added to cart it says out of stock. Glad your focus was fighting your own employees rather than technology. 🙄
You canceled my order. How am I supposed to review this properly?
Did I need a Magnetron Caribiner. . . No. Did I have to buy two so my wife did not get mad. . . Yes . . . . Thank you BD for saving my marriage yet again!
You can never forget to lock your carabiner with this lil guy. Been using the old version for almost 8 years with no issue. Glad they are back!
