I'm delighted that Valeriea has had a good experience with hers but my advice is,"Don't bother!" These things are getting cheaper and cheaper for a reason...ie they're not very well made!
For a start, if the bulb/element goes...and they do...it is not a case of just buying a replacement and popping it into a socket. It is not something the owner can do...unless, I suppose, you are an electrical technician of some sort.
I bought one and it came with part of the plastic base weighing about three ounces broken through. Did I just have to send that back? Oh, no! I had to repack the entire thing and send it all.
Fair enough, I got a replacement and was just getting used to and enjoying cooking with it, when the bulb/element blew a few weeks later. I decided to return it and ask for my money back.
As ever, one person thinks a product is the best thing since sliced bread and another wouldn't give it house-room! If you're a gamblin' guy/gal, go for it, but my advice if you do is...note how the items in the box need to be repackaged and don't throw anything away!
In the end, I bought a Remoska, which is a similar but much more substantial device, though quite a bit more expensive. Worth it, though.
