Surprised at how well it covers a frequently overlooked range of motion. Function was better than expected. Grip head is only a single 3/16" hole, slight disappointment there. 1/4-20 adapter is a big help. I added a 2" x 3/16" rod bent at 90 degrees to the kit so I could more easily set a small light to point down and out from a very low height. The middle riser is 3/8" so you can lift the two upper risers, heads and arm out and use the base as a high turtle base for the 3/8" Matthews system arms and heads. Micro menace arm anyone?
