Doesn't fit landscape mode tablet. It's got the letters on the numeric Keys which is helpful like a standard telephone keypad. The adjustable tone settings only apply when playing back not when pressing the keys. Nice to have would be ability to use the keypad without making tones until everything's entered and then be able to send the tones all at once. The playback of the keys that I selected went too quickly because the default timing wasn't set, and only 3 out of the 10 keys I pressed were sent during playback.
