I'll admit to having a love-hate relationship with these. They are of marginal quality (although the die-casting has improved recently) and unfortunate design (the adjustability is limited to four discrete positions). However, I do find the design and shape of the actual rest which sits upon your thumb to be quite comfortable...especially with a thin cork covering.

I have also been suspicious of the strength of these, but I have never seen one fail.

I recently decided that I would address the adjustability issue, because it is really the only material issue with these that I can identify. The existing screw solution is a thin thumbscrew with a slot, OR a screw with a straphook. Both have a cylindrical base that 'fixes' the adjustment to one of the four positions. This is necessary because the screw and strap hook are both pretty lousy to adjust. They are, however, just standard 3mm metric screws that require a precision length to engage the maximum # of threads without scarring the clarinet body.

I discovered that the panel-fixing thumbscrews on many electronic boxes are also 3mm threads. I searched around and found a very suitable alternative for virtually no cost; the ones I chose are black-anodized aluminum and they need to be filed a little shorter to leave 5mm of thread remaining; I chose aluminum so it would be easy to file. If you look at the attached picture, it shows the screw alone and in the application.

These screws can be purchased from Amazon by searching for:
<uxcell Computer PC Graphics Card M3x6mm Aluminum Alloy Knurled Thumb Screws Black 10pcs>

This enables continuous adjustment with very solid tightening capability with the fingers and, if I do say so myself, is more attractive than the original equipment.
