Pros:

• This reminds me of a memory game machine.
• This is a simple design, because it is wall-mounted, it takes up less space.
• It seems to be nice to be installed in a bar or a hotel lobby.

Cons:

• If you install it at home, you may be curious at first, but you will not use it more and more. In the end, there may be loads that are not used at home.
