I bought this to replace de original throw off of my old Ludwig Supraphonic snare, and it was a perfect fit. The mechanism is very sturdy, well built and better than the original one. The chrome finish is perfect, no flaws.
Bought this as an upgrade for an old Yamaha snare. It seems solid and nothing about the build suggest that it won´t survive years of abuse. It´s not a smooth throw-off, although I suspect it will loosen up a bit over time. Don´t expect it to perform anywhere close to something ultra sturdy and smooth like Trick or Sonor (Dual Glide), but it´s good for what it is.
