The Ox Locker will be a good locker someday. But not yet. The reports are coming in now about them grenading. Mainly the two unrealistically small spider gears inside. Like anything new, it's gonna take time to get it worked out. The Ox owners are having quite the time getting them engaged also. It's much like trying to shift a twin stick type tcase into gear. You need a small amount of movement and a small amount of luck. But I do believe that these lockers will be top notch eventually. It just takes real world testing to work out the bugs.
I'm on my second set of ARBs now. You must have a reliable air source to run ARBs. If I were buying new lockers today, I'd only buy ARBs. I would never put up with the quirks of an auto-locker on the street, and the Ox just hasn't been around long enough for me to trust it yet.
