    Love this product, it is fast and hods half a TB. Just be sure not to flip the button to off on the adapter or you can't add to or take away from the disc. I just had to flip the tiny button back down to be read and write mode. Well worth it at this price and so user friendly and top quality. It fits in the side of my laptop with the adapter included or can fit into the smaller port if you have one or just get a universal adapter for downloads from micro disc.

    Got this as the backup for the 1TB card for my 360 camera. This also came with the sd adaptor card. It was on sale making it a better value for the money spent.

    I know its way faster than i need for my switch but when you can get it on sale its totally worth it. Switch 2 is right around the corner and it makes me happy knowing i can use it on that if needed.

    Dashcam Storage Card at my fingertips

    Got a dash cam online some time ago and just opened it and started using. Like a lot of electronics, it was packaged less a memory card called a TF storage card. Was concerned this might be an old device, that is no longer provided in the US. However, as soon as I described I needed a TF card for a dashcam video unit. Was immediately directed to the camera section and met a great employee who showed me the packages with mini camera storage chips which included a cartridge for use with a standard card reader slot or computer slot. Great selection, terrific service and surprisingly reasonable cost. Decided on the 512 GB card, took it home an instantly recognized by my dashcam.

    Reliability is most important to me

    I purchased the scan disk and it works perfectly for what I am doing as far as recording media. I actually went back and purchased the two 1 tb external drives and one 2 tb drive that works on my Blackmagic camera for transferring large quantities of video data. They are perfect for capturing data from a camera because of their speed. And because they are ssd drives, they will make my life much easier. The best thing is that SSD drives have no moving parts. The reliability issue is most important because the minute you take the data off the drive and leave the set, the shooting stops, and the reliability starts. That helps me sleep at night without worry.

    It's a genuine microSD card from sandisk. It performs what it's supposed to. It's very fast and you don't have to worry about losing you files in it since it's very reliable. It's highly recommended if you want to expand your device storage. Overall, I have no problems and I'm happy with it.
