Worst design ever!,

This review is from: Fun & Simple Smart Electronic Sudoku Game with One Billion Puzzles for Ages 6-106! (Toy)
Probably the worst designed Sudoku machine in existence! Navigation with the 4-in-1 button is fiddly and forever requires correction (so forget any thoughts of speed-solving). The tiny numerical buttons are spaced much too close together - a normal-sized index finger spans all of 3 buttons, again requiring too many corrections. Entries in the top line are almost illegible due to the shadow cast by a deep frame (whatever the lighting). All numbers entered are 'thin' and far from bold and the cursor is difficult to see at the best of times. I am dumping this machine and will not even foist it onto a charity shop.
