Gave this as a gift. Recipient had to tinker with it slightly to get it working, but it DOES WORK! He loves it :)
This was not easy to put together even though I have done other kits. The laser pieces punched out easily. The illustrated instructions worked if you looked at them closely. By being careful I was able to place all pieces correctly. The result is quite a conversation piece as the bow of the cello moves magically by itself once wound.
A18 pieces are not flexible to make the curve. My first piece was barely made on it. 2d, 3d ones broke at the same location near the bottom of the Chello. The picture below is after I tried to glue back, it broke even more locations on A 18 piece.
It was a birthday gift to my young sister. She LOVED it! Worth the price.
This was an enjoyable project that required patience and diligence. It lived up to my expectations in appearance as well.
