Agree, I went from a Lenovo p2 to a ZenFone 6.
Keen retail pricing, dual SIM, SD card, so close to stock you wouldn't notice android, and kept the week long battery life. I hardy use a phone camera, nevermind the front facing one so the flip camera was better to me than the pop-up ones.
At the time it looked like it might convince Asus to expand their UK offerings.
Unfortunately the 7 and then 8 turned out to be more expensive and removed the odd feature or two.
Reminds me a little of Nokia of old. Occasionally a well spec'd sensibly priced phone would escape into the wild. That was clearly noticed because it's replacement would be a lower spec/features but higher price.
