Review on CLWHJ SD Card Reader - Versatile Multi-Function Card Reader/Writer for PC, Laptop, Smartphones, and Tablets by Vince Preston

The two units I have work great and complement my DVRs well. There are several free Android apps that can be used to connect this device to your mobile phone via the micro USB charging port. This is especially useful when you want to quickly view dash cam footage on your phone, whether those footage were recorded on a mini SD or micro SD card, which fortunately works for the vast majority of modern dashcams. These devices obviously have more features. used as that specific use but that's what I use them for and why are they in the glove box in each of my cars.
