Has anyone else bought this microwave. I've just bought it and unfortunately never looked at the reviews and there are many saying it doesn't sit level and it rocks corner to corner ie it's not steady. Anyway I've looked at the base of this and it has one rubber insert and nothing on the other three legs so it's bare metal sitting on my worktop which makes it too easy to slide and I think this is poor and makes it dangerous. I can't understand how samsung can let this design go past their quality control..
