Very similar item and not very common in the UK, mine's been on for less than a week and has a lot of watchers.
Theirs is a worse version on at a fifth of the price, but similar, and they have basically stolen about three different long sentences I have used to describe mine, and bunged them into their description.
I have sent a friendly message saying 'nice item, did you mean to copy bits of my listing word for word?!' Best wishes, etc.
Bit nervous now...but honestly how hard is it to write your own bloody description?
