The Dynotron and the Livewire (it's wiregate brother) are great carabiners that are good for what ales you.
It's semi-futuristic design may make it look a little chintzy, but it's not there for the bling - it's all about functionality.
The key lock makes it easy to unclip, the ribbed gate makes it easy to open, and it's strong.
