Very easy to install. The glass knobs are beautiful. Real glass, very smooth with no sharp edges or seams. The facets sparkle with the lights on. The brass plated metal body is very good looking, lightweight though, time will tell if it holds up well in a humid bathroom. The locking function works well and the handles turn smoothly. They have a heavy, quality feel to them when used, just like the genuine antique passage sets, but are made to fit a modern door. Other similar looking glass doorknoSee full review
