I just installed one a week ago or so. I like it, but it's definitely a bit of a different animal than the lock right (got one in the front D30). Make sure you pay close attention to instructions concerning lining up the paddle. It's pretty clear and if you follow the step by step you should be fine, but I've heard of people having the paddle lined up a little off and breaking them on the install, or right after. Just use the check block, rotating the carrier so you can check on all sides before and after installing the pin. If all is well there once your installed, you should be good. If the tire spin test checks out, and it doesn't bind up you should be good.
That said, mine does seem to be a little more hesitant to break loose on a slow tight corner than the lock right. I get a fairly loud pop every once in a while and a quieter, but still noticable pop quite a bit. Once it disengages, it's quiet (i.e. no ratcheting sound like the lock right), but it's slightly a more noticeable pop sometimes to disengage in the first place. I just tested it at a construction site the other day and it definitely locks up good.
P.S. first post for me, but i've been lurking for a while. I've had questions, but didn't feel like getting lit up as a noob and told to SEARCH! Turns out search actually works pretty good, but it's not much for rackin' up the post numbers.
