Yes I have. There is no brand marking on them so I believe these are Chinese fakes that are only 3GB that they flashed to make them report as 32GB and 8GB respectively. I also tried SDformatter on my PC to no avail. Windows had issues formatting these properly as well. They are faulty and/or fake. If someone needs them for the about 3GB of storage, they have more of a use for them than I do.
Just clarifying that these are not working properly and I believe these to be fakes from China. If you try to say I sold you something that isnt working or I described it properly, you will not win since I have said it my description and now in 2 comments
