Bests & Worsts Reviews from Amazon

Both Micro Center 32 GB MicroSDHC cards fail to format FAT, master boot. 1 fails every time, the other every other time. I get the same results using 2 different SD readers. These were Amazon Prime (but sold by: Micro Center) When I tried to return them via the Amazon, this note pops up: "This item isn't eligible for return". Why isn't this clearly noted on the product's Amazon web page ? I would not have wasted my time & money.
