Quality. The quality was just terrible. I by no means was expecting Swiss time engineering, but the quality was disproportionate to the price. For 85 I expected the handpieces to not be made of cheap aluminum. Just trying to set the time the handpieces got stuck on each other because they came out of the box bent. It’s not worth it for me to send it back and it does look good in the entryway but I will probably eventually have to spend more money to get quality handpieces put on.
