It's perfect. It saves on time and electricity and we haven't used our oven once since getting it! It's ompact but big enough for a large family (there are 9 of us). The only time we have any difficulties is when cooking a roast, but with a little forward planning, this is easily overcome. I'm totally in love with it - it does everything we need it to, and more!
Why only give it 4 stars, though? Well, I like everything to be very clean. This has some design flaws which mean there are places you can't get to in order to fully clean it. There are wire cages around the heating bulbs that cannot be removed to allow for deeper cleaning. Also, if a bulb blows/breaks, you cannot get those replaced - you need a whole new machine... Talk about a throw-away society! For me, these two issues would have been enough reason to have given it 3 stars, but I'm so pleased with everything else it does that I give it a 4.
