Advantages: Y6 Piano Black is a great looking phone with killer-specs. It runs smoothly with 4 GB of RAM - games like Asphalt Xtreme and Riptide GP Renegade (my favourites) are running with no problem at all. I am also very satisfied with amount of ROM - 64 GB will be more than sufficient for tons of apps, videos and photos. Overall quality is great, not to mention very generous package with headphones, screenprotection, phone holder etc.
Limitations: None so far.
