Great transfer speeds and storage capacity. Try to get this when it's on sale, at the original price it is over-priced

So far, the 2 256G cards I purchased have been reliable. When I received then, I placed them in my professional video camera and they reported different capacities. I formatted them but nothing changed. I called PNY. They told me that they guaranteed the capacity within a certain percentage of the stated size. It just looks odd to me when I see my camera reporting different capacities on the 2 redundant cards. They are probably fine. I might buy more of these since the price is good, but I will not use them in my camera because the different capacities just look odd. Otherwise, they seem to be fine.

Bought 2 dash cams and needed 'fresh' mem cards. Bought this 3 pack.They formatted fine and work well in both cameras. Using the 3rd with a usb adapter as a mem stick device.

The price is right and it records my ultra HD video off my Galaxy.... unfortunately, my Galaxy gets too hot and shuts down after 5 minutes. I'm keeping the card though.

I was looking for some micro SD cards to insert into my Reolink POE security cameras around the outside of my house. The cameras have the ability to overwrite the oldest data once they fill so I didn't need anything massive but also I wanted a descent amount of historical footage so I opted for these 64GB cards. At the time of purchase they came in around $5 a card for the 3 pack.The cards have performed well with no issues in the 4 months since I bought them. My home is in the mountains and the weather fluctuates wildly. This winter we had many days of single digits and below temps. We've had crazy wind and rain storms as well recently. No issues at all. I would recommend for the quality and value.

Exactly what I ordered.
