So I just got my zt0350 today, and being curious and impatient I had it apart about an hour after I got it. Disassembly and assembly is easy enough. But on of the inserts on the g10 scale that acts as a nut for the smaller screws popped out. It no longer grips the scale when trying to install the screw. So I put a dab of superglue on it and put it back. I know I could have simply sent it back, but I just got the thing and to me it's a minor issue. I'd be curious to know if when I do have to send it in they will have an issue with the super glued piece.
