Having bought this 2 months ago I was initially very happy with it, then a few things happened that turned me off it. In the middle of a game at level 8 the black queen was clearly checking the white king, and the computer did not register the king as being in check ???
The circular "enter" button on the casing is too loose for my liking and I have notions of it working itself loose or even breaking off in the near future if you do not treat it with the lightest of touches. The On - Off button has failed to respond several times. Finally, the whole thing has froze up twice for me.
