KEXIN 3 Pack 32GB Micro SD Card Memory Card MicroSDHC UHS-I Memory Cards Class 10 High Speed Card, C10, U1, 32 GB 3 Pack

Even though I have not used this product yet I most likely would have given a higher star rating if not for a little slight of hand maneuver in the discription. Goes to show you always have to go through everything very carefully before any online purchase no matter how small of a purchase. In the discription, 4th bullet down it clearly says "adapter included". But no adapter was included. For that you need to go down to the 6th pic where it says in smaller print "adapter not included". To me that's just not right to do this. This should be cleared up in which ever way you want but needs to be cleared up. And because of this "I would not purchase again".

I don’t know what it is about these memory card but they aren’t reliable in my application. It may be good for a tablet or phone but I have tried all three of these with a raspberry pi with frustrating results. In short the data becomes corrupt almost every shut down and power cycle of the raspberian os. This was determined by using 3 different brands (Sandisk, Samsung, and kexin) of cards following the same shut down sequence and OS. The kexin was the only brand that had the phenomenon of corrupt data causing the os not to boot. Knowing this I would be hesitant to store original content such as being used in a camera for taking pictures as the data may become corrupted.

Bought these for use in my Wyze indoor cameras, and they work perfectly. And the price was great.

I don't like that I have to spend my time reviewing this item.I have bought it,I have paid for it,I have received the product. I have not complained about anything. What more is there to say ?The product was good, the buying experience was good, but this is an intrusion into my personal time.I don't want to spend my time reviewing the purchase of an item. It is a pain in the ass - my ass, that is.

This was advertised as a U1 ( 10MB/s write ) SD card, but all three in my package tested over 40 MB/s write ( tested with 100MB sequential write using crystaldiskmark ) which puts it in U3 category. Read speeds were over 80MB/s.This is probably one of the few times that I purchased an inexpensive microSD that actually tested way better than advertised. Results may vary based on which lot you buy.Update many months later: It seems like the high read/write speeds on a USB3 reader may have compatibility issues and result in corrupted data . Using it on a USB2 reader lowers it back down to U1 speeds, but no longer corrupt data. However, one of the three cards totally failed after transferring a few card's worth of data and cannot be written or reformatted. This is obviously a lower grade product - but its really cheap - just don't use it for very critical applications.
