Yes, I got one as a wedding present. It worked really well for about a year and then the handle part fell off.
So, IMO, a good idea but not very durable. I still have the chopping board part though!
Also, the knife marks show really strongly and go very deep on the one I've got (in black). I think it is a bit unhygienic really with all those grooves full of germs, so if that sort of thing bothers you it's probably not for you! It also looks quite unsightly.
