Review on MXtechnic Connection Reader Adapter Mobile by Drexel Wortham

All connections work properly. The only reason I didn't give 5 stars is because there were no instructions on the box and when I plugged it in nothing happened. I wanted to return it as damaged, but researching a little more I found that I had to download the OTG USB File Manager app to use it properly. I have a Google Nexus 5. This app doesn't seem to be needed on other phones, but it would be nice if the seller stated that the app might work.
