I have had three of this type of oven over the years. recently bought the JML Halogen which doesn't have a hinged lid.
I have been perfectly happy with my original two and wore them out! This is the first halogen and I've had it now a few weeks and find it every bit as good. I really do cook everything in it.
Only using my oven when baking a large amount of stuff. for smaller things or one off cakes etc I do use it no problem, i put it on lowest rack, the main thing to remember is that it doesn't need to 'warm up' like a conventional oven and being fan assisted does cook faster.
I've had to 're-learn' a few things becuse I have found this being halogen, cooks quicker than my previous ones.
Would i buy another when I've worn this one out? Most certainly!
Would I buy from IW? No, but that doesn't mean I don't rate the product, I didn't get any 'extra's with any of mine other than 2 racks and tongs, but have never felt a need for them as you can use whatever you already have that fits and is oven proof. Nor have I needed the ring for any of them, but i have seen this on previous ones (the americans seem to like them, lol)
