Still good phones. Had mine 2 years and still going strong. I think Samsung made a hash of some updates so those having some problems could be due to poor software. Good price
I'm writing this on my two year old S6 which has been off charge since 9am and still has 62% battery left. Also never experienced any heating issues.
I would say the S6 Edge is good, we have 2 and after 2 years still going strong. Battery life not as good as new but no overheating issues etc.
