GetDpi is full of scammers. Always ask for a picture of the product + a piece of paper with your name and date.
Double check the picture if it's not photoshopped (I had it once) and if that's ok, just go for it!
I also got scammed years ago, you don't expect scammers for products like this.. but it also happend to me.
Since I use the photo method it never happend again.
