A little skeptical about the layout at first, but we made it fine. I am using more than that, after putting dampers in all the keys to make it a little quieter (not essential if known type). Solid construction, one flaw: the black plastic feet low quality, that leave traces on my desk. used on a Mac, do not worry after setting the arrangement of the keys in the system settings. The only key to this format in qwerty, to my knowledge. Note for users of vim have the esc key on the row of number keys is actually very convenient. I would buy the same without hesitation.
