Customer Ratings & Reviews

I had the SanDisk UltraPlus 64 gig, and nothing is wrong with that card. It works great with my phone and gopro, and it relatively fast. This card is all the good things about that card, but about 20% faster. I dont have all the fancy testing software to see actual numbers. But I transferred about 8gb worth of pics/videos I took on my gopro from the card to my laptop. On the UltraPlus, it took about 12 minutes to move everything over. On the Extreme, it took about 8 minutes. Thats good enough proof for me. $40 for 64 gb thats fast? I'll take it. Its also cheaper here than it is on amazon!

This capacity of 64GB is huge! I got it as a second card for my Autel Xstar Premium. At 4k resolution you needs lots of space and a spare card is always a great idea when shooting once in a lifetime video. Got it on deal of the day for a screaming deal, my only regret is that I didn't get two.

I bought two of these. One for my Samsung Galaxy S4 cell phone and the other for my Samsung Galaxy Tab S tablet. The cards are super fast and hold plenty of files. They work great with both devices. I was fortunate enough to purchase these during the Christmas sale ($35 each) which was an amazing deal.

This is a memory card-- and, while it is hard to write an interesting review for a memory card, I will say this: this speed level, and quality level, is about the only thing I would trust in my drone (which is what I use it for). It's perfect for my drone-- fast, quick writes, small buffer required-- finishes writing all of my video almost as soon as the drone is back on the ground no matter how long I fly. As for the price-- if this list price is indeed accurate, and not crazy inflated, then this also signifies a great deal! Other than that-- it's a memory card. You expect it to "just work" for a reason and it does.

I managed to catch this baby on sale one week for $59.99. I was looking to max out the expandable storage on my smartphone (Galaxy Note 3). The price was right so I took a chance. Essentially plug and play, the os on the phone recognized the expansion with no hoopla. Physical installation was a snap; I slapped the sucker in while I was still in the parking lot, lol. Powered up my phone, and bam....extra 59 gigs of storage available. No configuration required...slap the sucker in....and it's all there for ya. I've not had any problems, it's plenty fast...and I'm lovin it. Worth checking out if you're a smartphone user in need of some extra storage!!! Highly recommended.

I installed this micro sd card in my galaxy note 3. It works perfectly with it. The phone recognized it right away. This card has freed up all my memory on my phone so it runs like a charm. I watch a lot of movies on my phone and they are all saved on the micro sd card. Works great no lag what so ever.

I took 1080p and 4k videos with this memory card on a recent trip to Costa Rica. I have over 3 hours of video and more than 200 photos with room to spare.

I purchased this memory card alongside with a go pro camera. It was just the right amount of storage space I needed to hold my memories until they were transferred over to a computer. I would recommend this product to anyone who is needing a little extra storage space on any device.

Love my GoPro4 Silver - will be using it for video blogs on my website and daily shoots in general - great for live time and action. Customer service and knowledge in both the camera area and Greek Squad exceeded my expectations and is one reason I made my purchase at this Best Buy.

Good price for the memory and speed. Could be a little cheaper but still worth it. I did have my first one fry on me while it was in my phone (LG G3 Verizon) lost all my pictures, videos and music. I will still give it a chance and just make sure I back up my stuff more frequently.

As far as the memory card is concerned, I have never ran out of space before having to change batteries in my GoPro Hero 4 Black. I have even used two batteries on the same SD card and there's plenty of room, even while using 4k and taking pictures with the highest quality settings.

purchased for use with a GoPro camera. They work as expected. The 64GB card will hold 2 hours and 6 minutes of video when recording at 1080 at 60fps.

Bought this for a Galaxy Tab A as extra memory. Does exactly what it's supposed to. Completely compatible with no noticeable lag. Caught it at a great price too!

So far so good. Bought a faster read/write card because the dash camera has the ability to record HD video and I wanted the best possible outcome for the least amount of money. Will update post after I go through a couple of months of recording to see if video quality changes.

I purchased this for use in my Samsung Galaxy Tab S 8" tablet. I wanted to have the maximum supported space available. it is working well in my tablet and gives me the extra space for storage. I don't have speed ratings since I haven't tried to watch video from the card yet.

This is perfect for those who want more storage for photos and/or videos for their GoPro. And for the price you can’t beat it!

I use this card for my gopro hero 4 with protune and it works flawlessly. The camera doesn't shut off and my footage is always reliably recorded. Transferring the data off the card is super fast as well. This is a great high quality microSD card with lots of storage capacity.

This microSDXC card can be used as is (without the SD card reader) and is quite fast for use in my smartphone, tablet, and iConnect. I am told it can also be used in the SD card reader for my camera and video camera. without any lost of speed/quality. How cool is that?!!

The salesman recommended it, it was expensive enough to make me think it's good, and it has all these markings and codes on it. It will also be old tech in a year but it kicked butt for me on our family Caribbean cruise. Nice pics and good video imaging. I can't complain.

The 64GB is perfect for storage. Able to store many pictures, video and higher quality video like the 4K. Perfect buy especially when on sale.
