Excited but disappointed - TANDEMKROSS Accelerator Forward Thumb Ledge for Pistols

The idea of a left side thumbrest is phenomenal, but TK's execution of the final product is a bit disappointing. This thumbrest fits my Mark IV Lite perfectly and it came with everything I needed. That said, the finish is nowhere near what it should be. It's a very shiny gloss black, and matches nothing on my 22/45. Physically, it let's my thumb add stability, so I give it 3 stars, the finish is ridiculously shiny and it might aldo be somewhat larger and thicker than necessary. My guess is that its injection molded. Also, the lightweight torx tool almost immediately stripped itself when I attempted to remove the oem pivot screw. Glad I had a better quality [still poor] Harbor Freight Torx bit
