I have bought a whole set (even the biggest casserole dish- red one) and it is perfect!
Steaming is brilliant! I have used 3 levels Tefal steamer before, it was ok but it took quite long time to steam and water level needed to be checked quite often when I steamed many items at the same time but this one (Pyroflam) is perfect! Its also easy to wash- just soak in a warm/hot water for a while and its clean. I am talking now about casserole dish, as I bought a whole set :). We baked a few layers of potatoes, carrots, chicken, onions, cheese and mayo between each level and you can imagine how hard it is usually to clean such dish afterwards but with this one it wasn't! Of course you can use a dishwasher- even easier but I am old school, I prefer to wash pans in a sink. But its up to you :).
If you are still doubting- stop, and.... Just go for it! You won't regret it. Mum of my boyfriend is using this kind of dishes for ages already and she is still happy with it and dishes still look good. I hope I also be happy with my dishes years ahead:). Thanks for reading my review, I hope it was helpful :).
