Review on Alcey Micro SD/TF Card Reader Adapter: USB OTG, Micro B Connector for Android Phones, Tablets, PCs, and Laptops by Jay Chenier

It was amazing when it first came out and I was able to easily install my microSD card and read/write it from my computer as well as my Samsung S7Edge. My car had no problems accessing music through this device. Until it stopped working a few days ago. The microSD card is fine - I just plugged it into another USB reader and the device sees it fine. This adapter, on the other hand, no longer works with cards or devices that use the USB or micro-USB side. It just keeps getting mounted and unmounted on Windows when I try to use it. I've tried several known good cards with no success. Unfortunately this is outside the return window, this is a low rating as I have no idea what other options I have for such an obviously broken unit. Before this setback I liked the device - nice small form factor and worked well. Currently. direction garbage.
