Ah, I bought this almost 9 years ago. Used it for more than 7-8 years and then somehow lost it (rather I should say I forgot where I kept it). Never encountered any problem while using this product. An excellent buy I'd say.

Total Bang for the buck and worked perfect on my tab. Gives me 60GB of usable space. First time users of Micro SD card, be careful when formatting with old Desktops/PCs, most of them do not support SD cards with storage more than 32 GB and hence when formatting the card for the first time, dont get shocked if the system shows a 20/30GB size. Its no fault of the card and is becuause your device cannot support an SDXC card. Its highly recommended to use a device that supports a 64GB expandable memory card rather than an old laptop whilst formatting and stick to NTFS file format to have multi device compatibility( Which is why I am assuming one would buy a card with 2 diff kind of adapters:-P)

The product is undoubtedly amazing. Speed and transfer rate are awesome. Go for it. Disappointed with the delivery, the delivery guy marked as delived before i received the product. Without my sign he noted it delivered and i received an sms as same. Now feeling doubtful about making any payment beforehand, go for cash on delivery only.

Pros: Card reader and adapter comes in really handy if you want to transfer data using a computer. You can use the card reader as a USB flash drive / pen drive. The card is pretty fast. So Full HD video capture is lag free on the phones. Used this card for 4K capture on a GoPro Hero 4 and faced no issues. Cons: USB card reader / adapter is not USB3.0. So read/write speeds on a computer are not so great. Bought this for Xiaomi Redmi 3S Prime. Works pretty well. Available storage is 63.90GB as expected. Android users should first insert the card in the phone / tablet and format it first in the device. Only then should you use the card reader or adapter to put data in the card through a computer. Never format the card first in the computer or else the card won't be recognised by your phone / tablet.

I ordered this with fears of getting low speed and compatibility issue also after reading some reviews that says stopped working etc. Buy when i insterted this (strontium 64GB nito 566X) in Oneplus X. shows the available space of approx 60GB. (All my fears gone ;)) Now the main concern is, it read and write speed. Well i copied one file from internal to memory card (800 MB) it takes 26 secs. This is very good if i compare to my old sandisk class 10 (it tooks approx 55 sec) I am very satisfied till date no problem and card reader is also very great quality. Box contents - 1 Strontium Nitro 566X 64GB 2. USD card reader. 3. Microsd card reader. Conclusion - Go for it without thinking and also always choose the seller with great ratings this reduces the chances of getting counterfeit products. Mine is Genuine :).

I am using coopad which supports 64 gb sd.so i bought this item, first the card was showing sd card blank or unsupported system file i tried formating it but it was not working on my phone (only ntfs and i ext format was available) so i applied for refund and amazon responded immediately by arranging the pickup for next day but before returning the item i tried to format it with FAT32 and the result was clear it started working . so if anyone facing the same issue just format the card with FAT32 formating tool and it will start working . transfer speed is good as mentioned and available space is 60 GB.

Purchased the "Strontium Nitro 566X 64GB MicroSDXC UHS-1 Memory Card with Adapter and Card Reader" from Cloudtail on Amazon.in. Turned out to be a counterfeit. Please see attached pictures. I was very surprised to see a counterfeit being sold by Cloudtail. As far as I was concerned, I thought Cloudtail was the final word in original and genuine products but sadly it isn't. Just a few things to note about the product I received. - As seen in the pictures (hopefully), it came in an OEM-like packaging that was impossible to tell apart - The only way I could make out it was a counterfeit was because I had an original that I had purchased from Croma and I was able to compare the almost indiscernible differences. - The poor quality print job on the counterfeit was one of the things that gave it away. The top of the card (the one where the Strontium branding is visible) is scaly on the counterfeit. Even the sides of the counterfeit have residual ink flow marks. - Another observation was that the counterfeit was way thicker than the original. So thick that it barely fit in the card slot on the mobile phone (Note 3). And it did not fit in the attached USB card reader AT ALL. - The packaging the counterfeit came in was very OEM-like. It even had the importer's sticker. I've tried to capture most of the above in the images. Caveat emptors.

Attention, la carte est vendu non formatée. Donc 1ère chose, la formater. 2ème chose elle n'affiche que 59,1 Go au lieu de 64 Go. Je sais bien que normalement, nous n'avons pas réellement la capacité affiché, mais 5 Go de perdu, c'est presque 10%, c'est beaucoup. Une partition est indiqué not ready par mon partitionneur, les quelques Giga manquants sont surement là. J'espère pouvoir les récupérer avec Active Partition Recovery.

Good

I use this for my GoPro Hero 4 and it works great. When it comes to SD cards, they're all going to work, but some may get corrupted sooner than others. I've been using this one for about 3 months and it's fast. It lost a star because it gets stuck in the USB adapter every time i put it in there. It takes me a good 3 minutes to dig it out which is very annoying. But it all works and the USB adapter is quite convenient.

Perfect and works great with my phone. No issues at all. Its quite fast when copying stuff to it. Compared to my old samsung microsd 64gb this is way much better. my old card started giving me issues so i just switched to this card and no more issues since then.

So I saw all the reviews were positive on that and I decided to test it... Amazingly it was everything I was looking for, I'm using it in my Galaxy S4 and it's perfect, I haven't had the chance to do my high speed review reason being that I've only had it for bout 4 days but so far it's held up to everything I throw at it. I would recommend this to anyone looking for a good micro SD card to for their everyday use and the best part is the USB adapter that allows me to use it as a flash drive... Should've been USB 3.0 but I think I'm asking for a little too much there 👍👍
