The set screw that is supposed to hold the handle does not grab on to the threads (see pictures). Both, the set screw, and the drill hole, seem to have the proper threads but the set screw will not stay in place. I also find the location of this set screw is very awkward: Once the bridge is installed, it is impossible to adjust this screw.On a positive note, I like the fact that the intonation screws are metric (M3). However, I don't understand why anybody would use cheap Philips heads for these screws. They need to be replaced with hex sockets, which can be done as a cheap DIY upgrade.Unfortunately, without working set screw this will be a return item and I will be looking for a bridge that has a better design for attaching the handle
