Screw knob came off on first use
on March 28, 2009
The idea behind this clamp is brilliant. Unfortunately, the design misses on a key point: the knob used to tighten and loosen the clamp may be subjected to a lot of force. I clamped mine down pretty tight on a railing to be sure my camera was secure. When I came back to unclamp it, the knob simply twisted off. Upon closer inspection, the knob has threads in the center that screw onto the same threaded piece that holds the clamping foot pad. With very little force, it simply unscrewed itself since the foot had enough pressure to stay stationary. It took quite a bit of effort to get the the clamp off in the end because the knob would simply not stay on for me to unscrew. Perhaps there was some kind of glue and I just got a bad one. Not sure, but it has definitely rendered it useless for the moment. Perhaps some SuperGlue might work...
It is also worth nothing that this retailer has marked this up over twice what the MSRP is. Check B&H Photo or REI for a more reasonable price.
EDIT: After the discussion with Raleighphile, I'm putting a few stars back. The clamp really is a decent device, but I think the decision of not adding a thread locking agent to nut in the clamp is a potential design flaw. If you're dealing with a surface that is not slick, be sure to pay extra close attention to how hard you tighten it down. If you're cognizant of the limitations (or add threadlock like I did), it really is a decent little gadget to have, but loses two stars for forcing me to do what the manufacturer should have done.
