【5-Yrs Free Data Recovery】 GIGASTONE 32GB Micro SD Card 5-Pack, 4K Camera Pro, Compatible with GoPro, Wyze, Security Camera, Drone, Dash Cam, R/W up to 95/35MB/s MicroSDHC Memory Card UHS-I U3 A2 V30

Works great for audio recording. No dropouts at stereo 48K rates writing wave files. Got extra for sample library loading.

The only thing that is honest about the description of these are that they’re physically the same size as a micro-SD card. The transfer rate, load speed, record quality, and playback quality are all far less then claimed. They count on the fact 99% of people have no idea what the ratings mean. Try putting them in a DJI drone made after 2020 and you’ll know quickly. Once I received the errors stating “low quality as card, cannot record” on THREE separate drones, I did some testing. Read, Write, & Playback are not half of what’s claimed. I couldn’t verify capacity or data rate transfer rate because I don’t have that kind of time, plus, since they cannot record (be written to) at above 480P @2Mb, there’s no way to test this without finding an old camera and hoping they’ll work at any time. Besides, with so many “good” reviews, who’s going to listen? So waste of time to collect data when most have no idea what they’re looking for. If you want to save old photos or docs, I’m sure they’re perfectly fine, but recording straight to them at a higher quality, isn’t even possible if your equipment is recording at 2K or higher. I’ll assume the storage capacity it correct based on what PC properties state. Again, use for backup storage of audio, photos, or documents is probably great. If you know video quality, or want the specs implied on these, RUN (don’t walk) away! Hopefully your equipment lets you know when your putting sub-par storage in, or you’ll be very upset when you see what the end result. Photography & Video Recordings are memories that you cannot “redo”, and I mistakenly rolled the dice on these generic micro SD cards due to the price. Huuuge MISTAKE & lesson learned! Those claiming they work well in even a Go Pro must be using a GoPro 7 or older, or AGAIN, just because these stored the footage has no bearing on quality of recording (images), transfer rate, or record/playback speeds. Those that do claim these are great, need to print or playback one of the HD or 4K (lol) photos/videos on to a screen bigger than a mobile phone. Better yet, try printing the image recorded onto an 8x10 photo paper. Even better still, play back a video recorded to a 42” or larger 4K monitor/TV screen and you’ll see the pixels. I’m just thankful the equipment I used these in generated several warnings and made me acknowledge I was aware of their low quality before allowing me to continue attempting to record to them. oit of curiosity, I did acknowledge warnings, and continued anyway, just to see what would happen (and to make sure the warnings were accurate/not biased somehow). I’m so glad I knew beforehand not to record anything worthwhile, and didn’t get as let down once I saw the quality. If you just want eBay photos or even social media videos/pics, viewed on a tiny screen, they’ll also likely be decent for that. I don’t mean to elramble, just hoping to stop at least one person from making the same mistake, and YES, I tried ALL the cards, Yes, I pre-formatted before use, and tried reformatting again in alternate formats to verify these weren’t rated for specific formats etc. they are JUNK, and this is 100% false advertising. To put “A2”, “U3”, OR “V30” specs on these should be a crime, let alone “4K Camera Pro” (which simply confirms Gigastone’s intent to defraud. I even looked for fine print that should’ve been in description to say “not for HQ recording”, at the absolute minimum. Anyone that read this was warned, good luck, I’m sure it was just a “bad batch”, (which is how I justified my purchase after the few negative reviews I saw).

At a cheaper price this saves a few cents and saves great picture and good video

I tried to clone a 32 gig SanDisk SD card to one of these and it was short by a few hundred bites. For normal every day use this is a great deal, but do not expect to be able to utilize the full 32 gig if you try to clone an image. You would need to go up to 64 gig.

They work well in the beginning, but do not last. The number of writes to the drives before failing are very low compared to other well know brands.

Never used before, had good reveiws - a bit pricey but figured I'd try.

Beware these will go flakey after only a short time. Programs will seem to work with these but have weird issues, not saving a configuration etc. When you use imaging programs, Raspberry pi Image or Balena Etcher look out when verification starts, windows crashes and forces a restart. The cards will format fine but look out for the Windows crash.

All 4 boards I purchased failed with in a year. Complete Junk.

Fast delivery- does what it should. Happy
