USB mode no problems, full marks.
LAN mode full marks in use; more tolerant of Hibernate and standby than might be expected.
Win XP installation no problem.
Vista and Win 7; had to track down drivers as not on supplied CD. Could not find under "Integral P2 LAN" on AKASA site. Tried WWW with no success. Then flash of inspiration ; look under "Integral P2 PDAS" on AKASA website! Currently using akasa_ndas_3.72 (last in download list) with no problems.
A really good, cheap, product overall. But minus 1 star for the vista & WIN 7 drivers.
PS. product key on disk sleeve same as in device.
