Personally, 7up S80 1 is still good, with good quality, low price and high cost performance. The style is not lost to htc's mobile phone. However, if you buy online, I suggest you be cautious. At present, most of Taobao's mobile phones are refurbished machines. There is a painful lesson before. It is better to give a kind suggestion and go to a physical store. I hope I can help you!
