LONDISK 16GB Memory Card Class 10 U1 Micro SDHC Card with SD Adapter for HD Video Play/Smart Watch(U1-16GB-2pack)

It does seem to contain 32GB of storage, but it is VERY SLOW. Reading speed 2.43 MB/s and writing speed 2.60 MB/s.It doesn't seem to be a class 10 card, and is CERTAINLY NOT UHS-1 which can get speeds up to 90 MB/s as advertised. It is getting around 2 MB/s.****BEWARE!!! If you want this for video capture it will be laggy and may corrupt your videos!Tested with h2testw and SpeedOut, using the original SD adaptor (provided with the card) and without an adaptor.

I bought this product to use in the security camera. There was a purchase offer pack of two memory sticks which was a reasonable price. It arrived in an adequately sealed package, which every package included a memory stick and an SD Adapter.The memory stick (SDHC) has a capacity of 32 GB which I had to formatted to the camera's acceptable, so it took 2.5 GB of it, and 29.5 GB was free to use. It has a UHS (Ultra High Speed) speed class of 1 that gives you 10 MB per S speed of data transfer at the highest level that I believe is fair speed. The video speed class is not mentioned. It should have the same speed of data transfer. All in all, fair.

I used this product in my Olfi camera (like a go pro) to record video while on a horseback safari in Africa. When I got back and tried to download the videos the memory card corrupted. I’ve had to pay to buy memory card recovery software and still not got all the videos back. Don’t buy!

Not the best on speeds. Sometimes my dashcam gets frozen because of productivity of this memory card . Wouldn't buy it again but will leave it coz I'm lazy to replace it and i need one for my dashcam.Updated review....Stopped working less than in the month. Just went to tesco and got different one. Couldn't be ar**d to send it back , just throwed in bin

Bought these memory cards for mine and the wife’s new kindle fires and they do the job well, I’ve had no issues with the product at all. I searched on Amazon before purchase and read the revues and was impressed by what people were saying about the Londisk memory card, so on their advice I bought two and I’m very happy with my purchase.

I bought the "[10-year Warranty] Londisk SD Card 64GB Class 10 UHS-I 90MB/s Micro SDXC Memory Card with SD Adapter, for HD Video Play" card I spent an entire day loading it to just under 50% capacity with my files. All of them in the 1MB to 100MB size range. A read test shows 6MB/sec. This is very very slow for a card bought today and is 1/15th of promised speed. It doesn't look genuine to me (in that it doesn't look like the photo, with striations (parallel) lines and poor print quality. Beware. Returning.

Ordered this as a replacement SD card for my Raspberry Pi as it was malfunctioning. After testing in 3 different laptops, 6 different SD adapters, and the pi itself, it is 100% write locked and completely useless.

Bought one for my phone and it was so easy to fit and use, that I bought another for my tablet. I don't know about reviewers who think it's slow - moving photos, videos and apps on to the smart card speeded up my phone no end, and there is no perceptible time lag when accessing them
