Thanks to my knowledge gained in practice, i WAS able to confidently select this top-quality product for my setup... The clamping mechanism grips tight providing the stability I need for precision work, without compromising on comfort thanks to the ergonomic design. The knurled plastic is a great choice, as it's gentle on the hands during extended use. The only downside is that they could be more affordable, but you certainly get what you pay for in this case..
