I have no idea, sorry

better not to buy should of course mean

I have no idea if it's compatible, but I wouldn't advise buying it as the driver goes after one pass. I now use the old Schnitzler with my old Mum4 to chop vegetables. I have destroyed a total of 4 drivers with the 5 Schnitzler. Not exactly cheap. So better to buy!!! This never happened with the 4, it runs perfectly. By the way, a complaint on my part didn't help. It's supposedly down to the user, i.e. me. I'm just wondering why this never happens with the 4?
