I have bought this product and but could not use it for my purposes. Unused, in front of witnesses and in the original package I sent the item back. Sikogo I had asked for weeks to the legitimate refund. It was only after repeated requests Sikogo has refunded a partial amount and drew attention to scratches and dirt, which should have been allegedly caused by me. Without being able to prove this, shortens this seller lawful purchase price. I would never buy again at Sikogo something.
