Hi
Might just be my bad luck, but bought a Dual 859 a few months ago & no problems, pretty good machine.
Decided to get a 2nd, but appears to have been replaced by the 860, but bought one as they seemed pretty similar.
I`m now on my 2nd - both have had different faults. Asda are fine at exchanging/refunding, but I`m going to look around for an alternative.
