Psonsoi Memory Card 128GB Class 10 - with sd Card Adapter (Standard Packaging)

If there’s a rating lower than 1, maybe -1, I would have given it to this product. IT IS A USELESS PRODUCT AND A FAKE. Once you try to save more than 16GB, you lose any data that’s stored previously. I thought it was the ex-FAT format and I reformatted it as NTFS and it didn’t retain any data. I read all the reviews and was stupid enough to believe all the reviews that had “verified purchase”. Obviously it’s a scam and the worst part is that I didn’t realize it was such a bad product cause it faked me like it saved my stuff until I was already at the airport about to fly out of the States. SIMPLE ADVICE: AVOID THIS PRODUCT LIKE A PLAGUE. And I think Amazon should sanction the sellers....Ughhhh

Who doesn't want 128 GB for the price of 64 GB?. Tested it initially and "a few" errors were corrected. Then I tried to move all my songs onto the card so I could use it in my phone, and in the middle of the transfer, Windows stopped and gave me error messages. When I retested the card, it was full of errors. Glad I didn't have anything important on it.

While the card appeared to accept data, upon completion of downloading a number of my music folders, I found that the files inside the folders were absent. I was never able to successfully use this card in any of my phones or players as I always got error messages despite repeated attempts to transfer music files to the cards root folder. Clearly this card is not as advertised and given the low price, I should have suspected that it would not perform as expected.

Total Junk! Don't even bother buying. It worked the first time and that is all. Caused my Fire to freeze up, caused my Windows 10 machine to freeze up. Complete trash. It wont read or write and cannot view anything on it.

That is a fake 128 GB. After 14 GB uploaded a message will pop up telling you it is impossible to upload more of your files because they are not findable or corrupted, etc. You will have no problem to read the ones uploaded, but you might encounter problems with data. Very bad purchase if not the worst I have done on Amazon. That is a shame and his dishonest company gives a very bad image to Amazon after all. They should check. I should have read the previous reviews too.

this is not a true class 10 card. after testing read/write speeds ( 10MB/s minimum sustained speed required) this card only achieved a maximum of 9.06 well below the minimum of class 10. therefore I would only score this as a high scoring class 6 card.

This card is NOT 128GB I was only able to get about 60GB loaded on to it before it started glitching and corrupting data. I was doubtful about this card due to its low price tag, and unfortunately i was right. I guess it was worth a try. I'm returning it and spending my money on one from a reliable manufacturer.

Worked ok for a couple months. Phone recently came unable to read SD card. Can't retrieve any information from it. I have tried it in other devices and they can't sense the card.
