Customer Reviews of Ione Scorpius M10 Mechanical Keyboard - PS/2, USB
Not bad, if you get a good one.9/23/2011
This keyboard was once the cheapest you could get cherry mechanical switches, but more options have come onto the market. The main problem with the Scorpius has been issues with reliability. Apparently the circuitboards had a tendency towards poor construction. If you get a good one, it's a great deal, though.
