Product review (1 stars): No good.
Same issue as in the other review posted here. The thing starts making a 'knocking' or 'blub-blub' sound as it heats up. What's worse, the sound comes at regular intervals that for some reason are particularly annoying. Faster than Chinese water torture but slower than the 'clop-clop' of horse shoes on cement. I'm sending mine back to the retailer I bought it from. Don't waste your money on this one folks.
