It is handy and comfortable to carry anywhere. It is smaller than mobile phones. It provide 2300 mah battery which provide long battery backup. It is useful more than 20 devices at a time. I am using it from 2 months. I am happy with the device. It is weightless. Its internet speed more than 4G mobile phones. when its signal shows green then it gives maximum speed. so we can easily find where it work faster. It is lovable device. I love it
