My earliest recollection of this is as a little boy, waiting on the piano seat, playing with the metronome while awaiting the music teacher.  So I finally bought one, 50 years later. I have electrical ones but always wanted the mechanical ones. This has more features and durable plastic.  I hoped for it to be wood but I'd suppose that the price would include an extra decimal point. Like over 100 dollars more. So this will do. It's a precision instrument just the same. It will do all you need out of a mechanical metronome.  And here at Walmart,  they have cheaper electronic ones that really are the cats meow. They do everything.  I spent a long time finding out all it can do and it impressed me. If teaching piano, I can sit down and wonder about the child learning and have the same thoughts I did when I was the one meeting the piano and metronome for the first time.  Same design since the early masters. The placement of such all together is a timeless memory.

It's a good functioning piece.  Enjoy.
