I bought sandish 3.0 otg pendrive /flash drive as said that it will get hot but I didnt noticed that. reading spead was good as said 150mbps it wasnt that much but 130 mbps.
best is to buy 64gb pendrive
service and support is good
software was easy to install and it is fast.
the thing I liked the most is that this pendrive works really fast.
it is easy to use
