I have purchased this pendrive online.The pendrive is used to connect with mobile or pc both.It is a OTG pendrive.The speed of pendrive is very good.Its design is also good.It is a small pendrive which can easily lost so better put a key ring with it.The total space of pendrive is approx 28 GB which can be used to store so much data.It only supports NTFS format in mobile.It does not heated.The price of this pendrive is high due to it is otg and can be easily connect to any device.I like this pendrive
