I usually type with 2 , sometimes 3 finger in each hand . I be still a fast typist -lrb- for a regular guy who have not take any course or anything ! -rrb- but this keyboard basically force I to stop look at my finger every two seconds , and type with the correct finger , without look ! it be also incredibly ergonomic and comfortable !! wrist pain instantly go ! the only problem be that now I simply can not stand regular keyboard , especially apple-style laptop keyboard !! some people mention a problem with the spacebar be hard to push at the right edge . this be true , and it be a BIG problem ... but I try the fix that someone post in one of the comment here on Amazon -lrb- take out the key and twist the metal bar by rotate both end in oppose direction on its axis -rrb- and now it work almost perfectly , so YES IT CAN be fixed ! everything else be amazing . buy this . I should have buy it sooner . my wrist be happy : -rrb-
