All OK.
When i place the order i had choose 2 x 100 aluminium printed circuit boards in BLACK color but the store send me 2 x 100 in WHITE color .The seller must reply to me and ask if i want the white ones before they ship my order..Nothing hapens and i ask , Why ?? The reason of course is when the buyer place the order the Aliexpress organization look forward how to take the money and nothing else .Then the seller send what they have in stock without respect to the customer request. .Disadvantage is the receive time of order that is two days before the buyer protection time and exactly 60 days after i had place the order.
