Lenovo Flex 5 in-depth review

With the higher price of the new Yoga 520, compared to the older Yoga 510, we get not only apparent visual improvement but also a much better chassis, more comfortable input devices, improved portability and, of course, more powerful hardware. This is the stepping stone to the Yoga 720 and sells for roughly $150 less with the same processor. Interestingly, though, the trade-offs that come with the lower price tag aren't as many as you might think and maybe not that important to some users. [...]

  • Good build quality
  • Great input devices
  • Decent IPS display for the more budget-oriented configurations
  • The panel doesn't use PWM for regulating screen brightness
  • A lot of upgradability options for a 14-inch device (2.5-inch HDD + M.2 SSD slot + RAM slot)


  • Subpar battery life
  • The display appears to be a bit dim and color-deficient for the more expensive configurations with Core i5 and i7
