Very good design. Perfect manufacture
I don't understand how it could happen as I did not receive this items. On the post office they don't see it in the system and don't have it on the shelf. AliExpress somehow accepted receiving the post itself on my behalf. I am very disappointed.
I have got the items at fourth attempt visiting the post office. That is clear now that the problem was with our post service and I am apologize for my negative feedback about the saylor. Unfortunately I can not change it now.
