Sandisk Ultra micro SDHC Micro SD UHS-1 TF Memory Card 16GB 16G (Two Pack 16GB x2 =32GB) Class 10 Plus(1) Everything But Stromboli Memory Card Reader

I ran a full test of one of the two SD cards I received using the f3 command-line flash drive test utility, installed via Homebrew on my Mac Mini. I used the purchased USB SD card interface. The card and interface tested well: Avg write speed of 10.02 MB/s, avg read speed of 16.52 MB/s, and no errors writing/reading over the entire available 14.83 GB. A full test is slow (~40 min), so I only tested 2 GB of space on the 2nd card, with similar speed results and no errors. Next, I put one of the cards into a Zoom H1n audio recorder, formatted it, and did a few cycles of recording, swapping the card back to the card reader, copying the files to my Mac, and listening back. The card I tested worked just fine in the Zoom. At one point in this process, the card dismounted itself from my Mac (while I was listening to a copy of the file on my HD), causing a warning to appear about possible data corruption. But no data was corrupted on the card; it continued to work fine on both the H1n and my Mac in subsequent tests. My Mac had a bunch of other apps running in the background during this test, so for now I'm considering this an atypical event (though it may indicate a minor issue with the USB reader). Overall, this seems to me to be a very good deal on two solid Class 10 micro SD cards and a capable USB card reader.

One of my cell phone SD memory cards failed. The first ever for me. At about the same time my SD card reader had problems so I needed a new one. I'm glad I found this item in my search. One card to replace the dead one, one spare if any other fails. The reader is compact and just what I was looking for. A great solution at a fair price.

work great

The read works but it keeps falling apart. The cards seem to work fine though.

My TF Card in my Foxwell Auto Scanner became corrupt. Purchased these two TF Card replacements with the same 16GB Capacity and both worked seamlessly during downloading. Could not be happier with the results. Now I have a backup in case of a problem again. The USB Adapter for the TF Cards was good to have and worked well also.

Good high quality product for the precious pictures. These guys are fast when they record or read. At the end of the day, I'm fairly thrift for most things, but when it comes to storage for pictures, I invest more for the quality. You spend so much on a vacation and not to mention to precious moments that you can't get back. You really don't want an "error" to happen on the SD card because that just mean you lossed EVERYTHING on it. Spend that extra few bucks. Save on the one coffee on the trip and you will be glad, especially when someone in your party loses their photos because of a free SD card that they got.

So far so good, I will know more after several times used. So far they are 16gb and working. Hopefully they last a lot longer then those off brands. Just don’t use these for your drone 4k videos, there not high enough speed. You would need at least the class 10 V3 for high speed. But this works for 1080p at 60fps so far, there great for toy drone videos.

Because I ended up needing four micro-sd's I love this included a Stromboli.
