It seems like Tongfang never really test their laptops long term before releasing new models to public. The result is, almost every model has their own issues. Bloating battery, high failure rate+replacement cost of keyboard, low quality motherboard, burnt chipset/GPU, screen flickering, cheapo default RAM+SSD (some resellers do offer higher end SSDs), and the list goes on...

Yes they have a poor history of making poor quality stuffs. They had improved now, but their QA+QC still have a long way to go, compared to established brands. They have good engineering in performance testing, but not in long run testing...
