It hardly ever works. When it does make a couple of sounds, it barely moves and doesn't tell the time... it just flickers.

The noise is somewhat noticeable. Other than that, it's OK. They provide 3 sets of indicators to choose whatever fits best during application

I fixed the wall clock we had and it works perfectly, the only thing I had to do was to cut the hands because they didn't fit inside the clock but they are easily cut.

Reliable mechanism!!!!
