Okay, we've been using Sandisk products for many years. Our oldest card was 32kB (not MB or GB) and cost $69. We've had great results with their products (except some fake ones) over the years and this one is no exception. It's very fast (over 100MB/s in testing) and has been very reliable in use.

This card was perfect for my Samsung Phone. It worked with no issues and was very easy to install. I always try and get sandisk cards for phones and cameras.

These micro sd cards have been great for me. I am a vr videographer and use a lot of these. I will be purchasing more in the future.

It works perfectly with the GoPro Hero Black 5, no problems.
