Meanwhile, I have several of these and other adapters from Pro Photoshop / Timetrends24 in use and can only positive things. For example, I use the adapter to attach a greater production field monitor via ball joint to a 1/4 "mount on our camera. Even in the field, the thing holding the bomb, I have great confidence in the quality execution (may seem trivial, but if you expensive equipment has popped, then one pays attention suddenly on such things). The service is also super incidentally, if you take has a question to the seller (came with me before).
Therefore: strong buy recommendation. Price / performance earned 5 stars honestly!
