My daughter is 33 years old. When she was in the 3rd grade she peuhscad one of your clocks through her school. I do not know exacty what she paid for it since she purchased it for us as a Christmas present. However, it could have not been very much.The clock is 100% plastic annivesary dome clock. I just wanted to let you know in the 25 or more yers we have had it it has never lost or gained a minute and I only remember changing the batteries 2 or 3 times. We did loose the glass dome in our last move, but other than that is is working fine.You make a great product.Dick Kinney
