Summary: Just bought this from Asda £6.45! Using it on my laptop running on XP. Hardware recognised & installed automatically in a few seconds. Wasn't sure what the two side buttons were for but found that they scroll back to previous web page or forward (same use as arrows top left of Internet explorer).
Summary: Nowhere in the description did I see a mention of this mouse being RIGHT-handed.Surely this is very much a deal-breaker - if you are left-handed (like me and many millions of others) then you would definitely NEVER buy this mouse.
