I emailed the Q late last night and, unusually, received a quick response. It is aware of the incidents and wouldn't sell such an item - ? - and a collection has been arranged. Can I tell them whether I want a refund or replacement. Thankfully, it is out of stock, as any replacement would be from the same batch of faulty burners. I wouldn't have thought the Q would offer this as an option, it could be leaving itself wide open to multiple lawsuits. It is a shame, really, as I quite like the fact that it illuminates. I couldn't possibly risk using it, and feel the Q ought to do a recall. Perhaps allowing us to keep the melts, gratis, as compensation.
