I was concerned about buying a chiming clock online without hearing the sound but I was delighted with this one! It was very easy to set up and within an hour, the Ave Maria chimes and bongs were correct! I love that you can select if you want constant chiming or off during the night. It runs on batteries so no winding! The pendulum swings beautifully. The clock is very light and initially that was a concern when I read the description. I was worried that such a light product wouldn't have the look or stability for the price I paid for it. But it does. In fact, since the clock is light, I was able to hang it and be certain it was secure and not likely to fall and be damaged. A great product.
