I have an R11S. Very happy with it. I've been looking at the R15 with interest, but I can't justify upgrading to the new model when the older one is still a great phone. Screen is fantastic. Battery lasts a couple days. Also has a micro USB port, its only downside for me. Also has fast charge, 5 minutes charge for 2 hours talk time is pretty cool. I hear people bitch about Color OS, but honestly, I find it intuitive and quick. Predictive text is not especially good though. I love it, no plans to switch at this point. Its also a very attractive phone IMO. Great phones, but I'm not sure they fit in this thread, they are neither cheap or pieces of crap. Just an IClone when it comes down to it, not unlike the Iphone X but waaaay cheaper and with a superior screen.
