Cool 1 dual is one of the best budget offerings when it comes to chinese smartphones but some cons on this device might affect the buying decision as well.Talking about the build quality of the device the cool 1 dual is made out of metal and feels premium in hand. The performance is also superior than its counter parts as it has the Snapdragon 652 with 4gb ram.The battery life and camera are also good for the price.but lets come to the cons.firstly the ui is pretty awkward and new users might find problem and also the phone is bad in terms of updates. Otherwise it is good for the price
