about 18months ago a couple of people were using them regularly but I have not seen them on here for a while, All the reviews I read back then were positive. From memory they had a real PSA look to them once graded and they had a really good grading report telling you how the grade was given.
I heard they are good with Aussie sports cards. I don't know about NBA cards and if you were to sell NBA cards with them overseas may decrease the value of the cards?
