Lenovo zuk z1, people now a days thinking ?? that this model got an old Chipset but the thing is, the other related phones in price segment of 10k and above are getting low performance compared to this one. Its 801 Snapdragon Processor Man! Clocked at 2.5 Ghz, 3GB RAM, 64GB ROM, I am using it since 8 months but am happy to having it. Dont neglect the old ones
