I just bought one and it's broken (think burning smell and a little melted plastic where one of the batteries goes) and I had it running for just a couple of seconds. I go to try and use it on my feet and nothing apart from the horrible smell. Grrr....
It will be going back tomorrow, but are they all this rubbish (which would explain why they so discounted) or was I just unlucky? I'm wondering whether to insist on a refund or try again with another one.
