I have been using these cards on IP cameras for years and they work great. I don't expect amazing speeds because they are a basic category at a very low price.

It was on a dashcam (car camera). Very fast indeed, but it "died" exactly after 1 year. I didn't even bother with the warranty, I preferred to buy a card of a different brand (high endurance for more reliability). Unfortunately, it is not reliable (at least not for continuous recordings), and I see many people in the reviews with the same problems. I would recommend avoiding it to keep your mind at ease.

Perhaps the best memory card for its price, I have had it for 5+ years and have used it in 2 phones with countless read-write cycles and it still remains fast in both reading and writing. Maybe its performance has slightly decreased, but personally, it doesn't bother me. As for reliability, the name SANDISK says it all.

I don't know why, but mine that I bought from a store, not from here, turned out to be faulty. Even though it tells me that 9GB out of 15 are being used, I can't delete anything or add anything else, and it's not my phone's fault because I tried it elsewhere and the same thing happened. It's a piece of junk

For basic uses such as expanding storage space on mobile phones, tablets, etc., it is a very good choice with good speeds and very reliable, having the guarantee of SanDisk. Of course, okay, up to a point, now for cameras that will inevitably shoot in 4K and anything more demanding, then it is not suitable because there are SD cards for this use. Specifically, this one is aimed at the audience that simply needs an expansion of storage space. I recommend it and it is undoubtedly one of the best options for this use at this price.

First of all, it is really very fast memory. 10 frames per second 24mp in raw format at least 30Mb each and you couldn't tell anything. However, suddenly without any sign, it burned towards the end of a trip, resulting in me returning without any photos.

I bought this SIM card today for a ZTE A310 smartphone model, I inserted it and immediately it was like I got a new phone. With my previous one, a Transcend, it was terrible, the phone was very slow and kept freezing, it also had an issue with the internal memory, it had less storage and it took over 10 minutes to transfer a 20mb file. Now, with this SIM card, everything is great, the phone works perfectly and I finally understand the difference with the quad-core processor that the phone has, before it was like having a single-core processor. As for the reliability of the card, we will see, hopefully it will turn out good, it also has a 10-year warranty.

UPD: Unfortunately, it burned out this year, I had it for 3 years, it got completely blocked, couldn't even format it, nothing worked. All my data was lost, couldn't delete or write new ones

The most economical branded card on the market, with 10(!) years warranty and flawless operation. 100% Value for money purchase.

For its cost, it's fine. Don't expect crazy speeds, it's for simpler and not professional uses... It's a good reliable card and with the Sandisk warranty, I've had it for over a year, loading it every day, and I haven't had any issues until today.

Excellent memory card. It is truly one of the fastest I have purchased. I use it in my tablet to store files, but I am also considering installing applications on it. I am very satisfied.

We bought two memory cards, one for me and one for my wife, in September 2016. One of them broke and the second one is ready to burn out, and it's causing my S7 Edge album application to freeze. What can I say, guys, maybe we just got unlucky.

Very good and cheap solution. I haven't had it for long, only 1 week using it on my phone (Samsung Note 3). It has a slight difference from the Sandisk Ultra microSDHC 32GB Class 10 that I had for file transfer (it is slightly faster).

I believe it is a good purchase.. fast compared to other memory cards in transferring to the computer and in reading. I bought it for my GoPro action cam. I give it a 4 because I haven't tried anything else yet and I've only had it for a week. Also, I bought it for 18 euros while you can find it cheaper on Skroutz.

Edit: 21/4/19 With my GoPro Hero 5, I was getting an SD error.. (in 1080p recording) but I changed the card to an Extreme SanDisk and I haven't seen the problem again.

+Speed
+Smoothly records 60fps 1080p videos
+Perfect for mobile and DSLR
+Does not easily overheat

Tip: It is the ideal SD card (and for its price) for mobile!

Update 8/7/20 - 3.5 Years Later: I still have it and it still has excellent speed! It's like time hasn't passed at all. I would buy it again. Worth the money

Almost two years now it has never let me down, fast and for its price... one of the best

Reliable solution for now, it has not caused me any problems since I have used it in the past.

Recent purchase.

Very good product - excellent response.
