Review on 📱 Mini Portable Micro USB OTG Adapter with 4-in-1 SD Card Reader - USB 2.0 Port & SDHC/TF Card Slot for Android or Windows Phones (Micro USB Card Reader) by James Thakur

This device seems very cheap. The USB port is short and doesn't fit in thicker phone and tablet cases. It fit my Samsung Note 10.1 tablet very well. While the tablet eventually recognized it, my phones, including the Galaxy S3 and S5, didn't. While it works on some devices, there are other adapters at the same price that work better with higher build quality. On one of my devices that it worked on, the transfer speed was slower than it should be for USB 2.0, leading me to believe that there might be a USB 1.1 driver in there. Pros: I think it works sometimes on some devices. Cons: Cheap build quality. made of thin plastic. Short and solid micro USB connector. Doesn't support a range of devices that should be. Transfer speed is slow compared to other available options.
