Summary: This is one of the better MicroSD cards which I have seen. It is Class 10 which indicates that it has a transfer rate of 10 Mbps. The packaging comes with a MicroSD to SD card adapter, which means you can use this as a Full Sized SD card as well. The packaging also showed that it has a speed of 30 Mbps which is only for read.
Summary: I did research on the write times (speed) of different cards and this one came out on top. There is a noticeable difference when shooting with my Nikon D5200 when compared to shooting with my other SD cards.
