I got my Chuwi Herobook 14.1 and was very happy with how fast it is, how it connects to wifi, and overall functionality. So I would have given this a five star. It's really a great, fast, work horse computer. However, when I started using it I found that it only has a batter life of around 4-5 hours, and its promoted on the Amazon site to have a 9-12 hour life.I bought this computer for $399.99 over all other computers for that very reason. I need a computer that lasts a long time.So, I'm very dissapointed witih this. I wrote the seller of this to complain and I never heard back.
