Very nice product, simple to use, was a bit surprised at how small the inside was though, but overall very nice and very happy with it.

Replacement Baumatic microwave

Bought this new model to replace rarely used previous one (also Baumatic) that blew up just after guarantee expired! It was more cost effective to buy new than repair old, new model works well so far
