Three months in and mostly happy. The 2.5 inch door knob suits our doors. Only downside: looks fine, just plainer than I expected.

Ordered 20 and they all matched. Size is spot on - we measured first and it fit perfectly. The black is a great modern touch against our white tile. Exactly what we wanted.
