Yep my Dvarw clones are flawless too. In fact of all the clones I've bought over the years from FT this is the first with a problem.
Anniepan has replied and a refund is underway. Better still they've also passed my comments and photos on to the manufacturer.
FT have always been good with their CS in my experience.
The main reason I kicked up such a public stink about this is the safety aspect otherwise I just would have opened a ticket and sorted it out through the usual process.
