Hey I have 2 of the YOTH Ducky Mini (MX Reds and MX Browns). I think the build quality of the board is pretty solid due to the aluminum. But for a 60% board, the price tag that it comes with isn't quite worth it. It's almost twice the cost of a Poker II and I wouldn't buy it other than for collection purposes. The height of the keyboard is pretty flat if you get what I mean. The Poker II has a slight angle in the case which gives it a nice height but the Ducky Mini doesn't have the same design with their case so it's rather flat. The board has a mouse cluster which is pretty nice for using whilst on the go so like maybe on a train etc. The function layer of the board is essentially used to swap the key priorities like swapping the tilde with escape etc. (No dip switches). There is also unfortunately no programmable layer to the keyboard either so you'll be forced to used AutoHotKey if you wanted to reprogram the board to Colemak, Dvorak or something else.
Also if you intend to mod the board at any point such as swapping cases etc, the Poker II > Ducky Mini any day.
Hope that helps.
