The Accuratus 595 from Ceratech is a compact sized keyboard with 12 embedded function keys. This design of the 595 always gives the impression that the keyboard is bigger than the measurement suggest. Whilst having 89 keys the 595 (as with many other mini keyboards from Accuratus) has the ability to emulate 105 keys. The 595 uses the same ultra reliable membrane technology found on other Accuratus boards.
