“Unusable”

“This carabiner is rather small for a "jumbo" model. It's smaller than a BD Rocklock or Petzl William. It's just a medium sized HMS locker. The real problem is that there is a dangerous flaw in the auto "locking" sleeve. This carabiner doesn't lock securely at all; it's locking mechanism is completely ineffective and unsafe. It is very easy to push the gate open with a light side load from a finger. I wouldn't trust it at all for use as locker -- in which case it is just a rediculously heavy non-locker. Don't buy this item; buy one of the other Simond lockers available. All of the screwgates function well.”
