Really tiny and useful. Just inserted into tablet and later on the phone to send some pictures from one to the other. Read speed is great ! Over 100Mb/s ...I got 130Mb/s in notebook. Write speed is a bit dissappointing to me.

Good OTG drive. Getting a write speed of 5 to 11 MBps. Great price. Got it for 622

Brilliant little device, serves as backup drive and adapter for phone to computer,great value for money.
