I buy this as a replacement for I Dell keyboard . it look good and really be the same design as the Dell , however its not comfortable for my hand at all . not really sure what the issue be . I do know that its too low to the table even with the little flip thing up , and my finger seem to be reach differently . I have arthritis in both hand and by the time I end my work day , my hand be very tired . this do not happen with the Dell keyboard . I imagine it would be fine for people without hand problem .
