I recently purchased the Wingostore 30-note music box from Amazon. The gears are copper and I felt that getting this would last longer and be more durable than the Grand Illusions plastic gears, and likely prevent slippage. Unfortunately after a very short period of time, my gears are making a squeaking noise after every revolution.
Has anyone else experienced this with the copper gear models, and is there a good way to fix this? Is it better to just get the Grand Illusions music box instead?
