Patriot LX Series 8GB High Speed Micro SDHC Class 10 UHS-I Transfer Speeds For Action Cameras, Phones, Tablets, and PCs

Doesn't work. Installed an OS on 3 of these and all three work the first boot but after that nothing. When you put it back into a computer it doesn't read anything. Card is not detected. If you reboot it comes up with an error saying the drive needs to be formatted, has no readable data. I have installed this OS on a few other brand SD cards with no issues.

Horrible! Don't waste your money! I bought these for my kids kindle fire that was running low on storage. I put a card in & it instantly says that there is no sd card inserted. Um yeah I did. I know how to do it. It eventually worked but then when I go to transfer some games to it, the games would no longer work. They were grayed out on the home screen & you had to redownload them in order for them to work. Then when going into the kindles library it would say "app not available". Did that to all 3 kindles. It would also kick the kids out of every game they tried to play. Not happy!

These do not have a great success rate. I ordered 10 (2 Five Packs) back in July of 2019. I use these for home cameras which will auto delete videos to preserve space and keep a constant feed of historical videos. Leaving enough space to continue onward without issues.Out of the 10 SD cards, 2 work to date. Not good at all!I've attempted to recover or reformat the data on the 8 SD cards but all are unrecognizable via all the devices I've installed them on, be that PC, Mac, other cameras, phones, and you get the point. They are junk and do not work.Overall I'm very unsatisfied with the quality and while I understand SD cards have their issues, 8 out of 10 is not a great success rate. These have all failed in random durations, so not all at once, however all over a period of 4 months...I would recommend going to a better brand which has a high success rate.

I buy a lot of memory cards, and these are a terrific buy. The 5 star rating is based on value (you can get cards that run faster but cost a lot more). I like the flexibility of being able to use them in my Tascam DR-05 digital audio recorders (which require micro-SD cards) and in GoPro cameras and also use them in my Nikon and Pentax DSLRs (with the included adapters). While the trend might be to get as high capacity cards as possible, I prefer using multiple cards and not have all my eggs (or images) in one basket. Good and reliable performance at a very affordable price. [Patriot LX Series 32GB Micro SDHC - Class 10 UHS-I - 5 Pack (PSF32GMCSDHC5PK)] I bought this at normal Amazon prices without manufacturer discount or endorsement fee for this review.

These have proved to be a bad choice. They work as expected for about a week before they failed. Not recognized by anything once they go. I have never had an issue with micro SD cards, till these. They were purchased through Amazon. Never never again.

I loaded all five 32gb with the same folders of long mp3 songs to find out how far before total capacity. Three loaded up to 32gb, one loaded up to 16gb, and one loaded up to 4gb. I don't like the deception, but for $21 then i will not complain, but i asked Amazon to have an SDcard page that you test your cards the day you get them. I copied the same folders of mp3 music until they filled up; 3 cards were 32, one card was 16 and one card was 4. Since cards are either 4 or 8 or 16 or 32 then when you pass each gb level you know the card is yet double what you put on it. Once your directory says 27 free of 32 you know it has 8 because it is over 4; once it says 23g free of 32 you know it has 16 because it is over 8; once it says 15gb free of 32 you know it has 32 because it is over 16.

As a semi-pro photog I’ve used patriot SDHD memory for all my photography and have never had an issue with any of my several dozen cards & I don’t expect any issues with these micro cards.For a micro SD card ... although larger size can be had - I think you’ll find a lot of devices like security cameras only take 32gb’s anyway. And if you decide to use the handy SDHD adapter for your regular size SD card devices - i believe you’ll find it to be plenty, especially if you buy this extremely well valued 5 pack. Speed of cards is also very adequate.My only problem, which is not with the card itself - but they’re so dag-gone small... when I went to press it down into our security camera’s slot my finger tip slightly slipped and the slot spring popped out the card somewhere and I was never even able to use it.Despite numerous attempts- I’ve still never found it. :-( (grumble) LOL

I tried uploading files to this card: and it tells me that it's copywright protected. So I remove the card from the card reader: slide the switch into the opposite position: and reinserted the card into the card reader. And: it tells me the very same thing! I can't put any files on to the cards I tried inserting the card into another san disc converter that I've been using for about a year: and I get the same copywright error message! I'm going to ask for my money back: ASAP!
