Sky Seller is 100% legit. And no, I wasn't paid to write this. In fact, I paid them.
The product came exactly on time and the quality was as promised. I am very, very pleased indeed and that's why I am writing this review.
I should add that it helps if you know exactly what you want. I was also lucky that it fitted perfectly.
When I missed the first delivery, they extra notified me about it via email. That told me that they care about their customers. If you're on the fence, I say give it a go!
