For people like me, applications like these are a boon. It takes very little memory on device and is capable of ridiculously fast downloads( once I diwnloaded a movie of 108mb in just 12 seconds) .
Also, it remembers your passwords that you can forget. Its highly optimisable. Easy in operations. Ad blocking is the best feature and I just love it.
If you are having an android device UC is a must have.
