I just hope you have better luck with it than I did!
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 for replacement? 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 cooking with it, when the bulb/element blew up in my face. Of course, you cannot just buy a new one and fit it yourself, so I decided to return it and ask for my money back.
Clearly, these things are of poor quality for one reason or another, so I now have a Remoska...quite a bit more expensive, but a solid and dependable piece of kit.
Of course, you will almost certainly get someone else here replying that they are the finest thing since sliced bread and that theirs has been functioning well for years. My advice is...make a note of how the packaging goes together and don't throw it away!
