This shop is perfect if you know how to use it properly.
At start, i didn't know how to use the website and I got a few dead cards for which I couldn't get a refund because I didn't use the check and report buttons. they refunded only one of them when i opened the ticket about it and told me to use report button for next time.
So i figured out that the best way to get a live card is by using the checker after you buy a card which is available for 2 mins and if it says alive then you have around 5 mins to verify the checker results. If card is dead then you can use the report button within 5 mins to always get a refund for a dead card.
I bought 27 cards in which i refunded 4 dead cards and 3 were not refunded because I didn't know about the report button. I even got 800 dollars from one card. And every card had good balance in it.
Overall, it is a good and clean website with good material.
You just gotta know how to use it
