It works and is compatible with my old SMEG cooker
wiring layout is slightly different to original timer in my SMEG cooker, but I was able to work it out. I had to play about to set the real time - it turned out to be a slightly different combination of buttons to push than on the original.
It could have done with some user instructions to be supplied.
Apart from that it has a nice bright dispay and so far after one week of use it is still working
