I have had only a single problem with my Nexus 6, as far as hardware goes: the USB port on the bottom sucks. On the other hand, there is an obviously superior way to charge the phone, since it supports Qi charging, which I have stations for at my office and home. I only need to use the port when flashing a new ROM (it works, but only in precise alignment).

You should provide some actual claims about the problems you had with the hardware rather than just complaining.
