Nice big biner, easy to work the gate. Note it's just a double action, a half twist on the gate and it opens. The spring on the twisting action is a bit lighter than the Black Diamond equivalent (rocklock autolocker), which is a slight negative in my book but no big deal. Only real downside is it's quite heavy. But I don't think anyone else sells a big autolocker like this for so cheap, so if you're on a budget it's a solid choice.
