As I'm recovering from shoulder surgery, the W.R.I.S.T. system has allowed me to play the oboe much sooner than I expected (with doctor's approval of course!). It takes all the weight off of the thumb/arm and allows playing in a relaxed manner. It is well constructed and easy to use. A great find!

The W.R.I.S.T weight support system works quite well. There are two things that are not clear from the directions 1.) if you are attaching to a smaller music stand (such as the portable ones) you’ll need to flip over the removable part of the clamp - it’s designed for this option but the directions that come with the unit don’t mention this . 2.) you don’t need to turn the brass screw itself to adjust the spring flex - just push the screw head to the left or right (following the coil) to move the interior rod backwards or forwards within the spring assembly. (This is hard to describe - maybe that’s why it’s not clear from the directions). This is a beautifully designed mechanism , and I’m very happy with it.
