The widened end groove is exactly what I needed—it gives each slide a satisfying, controlled stop instead of that loose, rattly feel. Took it out during a long train ride and kept reaching for it the whole time.

The widened end groove really delivers that solid, controlled resistance I was hoping for—it glides with a satisfying weight. I've caught myself fidgeting with it during calls nonstop. PEEK track feels super dense and premium in hand.

The PEEK material feels dense and premium in hand, and the widened end groove adds just enough bite to make each slide satisfying. Took a few days to break in, but the resistance is now nicely predictable. Solid buy for the price.
