Review on 🧩 UGEARS Wooden Box Construction Puzzles by Otto Suarez

This is a relatively new product and should not be purchased for several years until it is improved. After following the instructions very carefully - even ripping open the exposed parts to find what binds - some annoying bugs were found. The "Code" setting on the back determines whether the key can be side-inserted (or not). Using a code to lock the machine may not be necessary, but the device is assembled in a locked position and the instructions say nothing about fixing this problem. When the left anchor moves forward, it moves the coin counter back (therefore an accurate count is not possible). Coins dropped into the cash register do not end up in the shopping cart. Instead, they land on a ledge and the cash register must be tipped forward for the coins to fall into the recovery box. Yes. I also found the paper bill validator to be clumsy; It didn't work as smoothly as shown in the video. It's an interesting looking piece of junk.
