I bought this a year back and I am greatly impressed by this device. First it has a great colour. Its slight fat looking but this means nothing when we come to its battery life and battery charging feature which is truly great. It has fast charging option which works great even on the devices that dont have turbo or fast charging system. I have oppo f3 and it doesnt support fast charging but when needed in emergency or the battery is about to die. This device charges up my phone very quickly. My recommendation is that overall its a great device to go for. It has a great value for the money that you pay to it.
