I purchased this keyboard (Womier K66) and received the Womier K61 as a present. I would NOT recommend either of these Womier keyboards to anyone wanting to actually replace the switches or modify either board. Both of these Womier boards have a switch hole so tight there is no way you are able to remove the switches without breaking them, or if you are able to get them out at all (I attached an image).
I did receive a replacement for the K66 version of the board and the replacement was different enough that the switches did not break apart when taking them out. However, both Womier keyboards do not allow ease of hot swapping.
If you are looking for a board that you are sure you will never want to replace the switches on and are looking for a cool RGB style, then this would be okay, but there might be serious issues if you ever want to make any modifications to this board.
