Now a days as you see all mobiles available in the market are of high cost with low feautures, but the lenovo vibe k5 note is the best mobile under low cost because it has good sound reception technology which is very important and very ease to use even a small child can also use it and the battery durability is awesome and all the feaututes and options are very easy to understand.coming to its style and design the screen is awesome with feather touch and edges are round so good glass is very hard so the chances is less to break and the important thing we require in the mobiles is ram if the ram is less the mobile will be slow it irritates us but in this particular mobile the ram availability is 3GB means the mobile is jet speed and the required amount of internal memory to store our files and expandable upto 32GB and the battery is of high mah means the battery lasts long and the money is also very less compared with the other mobiles of the same feautures if any one asks me what is the best mobile with low cost then surely I suggest lenovo k5 note.
