I did a review on a Hottop back in 2005 and they forgot to charge me for the roaster...well not forgetting but the review got a lot of coverage for them and they were delighted. I did keep waiting for the invoice but it never arrived. 12 years on it is still working. It is dead simple to use and always gives a good result, it is hard to fault, except for the price which is rather high but it is a great product. I've never had a single problem in that time, just replaced filters thats all.
