It's a modern Android smartphone with a (supposedly, notebookcheck is less accurate than we had assumed) PWM-free display, which pretty much warrants investigation these days. @khaneric and @Dominic had preliminary success with it.
Some users having success with a device overall increases the chances it may be OK, but far from guarantees it. We are not a heterogeneous group and have different triggers. PWM is only one potential trigger (and some people can tolerate certain implementations). We also think that a lot of supposedly flicker-free devices have flicker in the form of dithering, LCD inversion, font rendering shenanigans... This is why it quickly become very expensive trying many devices. Make sure you are aware of return policies and shop accordingly.
There is a chance it may be comfortable to look at. In my experience, there is a slim chance any device will work even with positive references. That's how bad things have gotten with this technology. Be prepared to go through many devices until you find one that works. If I had the cash available and possibility to return it, I would have already tried the Nokia 8.3.
