I bought this replace an old HP DV9730 as my go-to laptop.  These two are completely different in terms of processing power and capabilities, but I paid close to $1100 for the HP, and $279 for the HeroBook.  Do not think you'll be getting a world-class laptop.  The Chuwi seems to solid, light and capable.  I've added and additional 256G microSD card in the external slot to give this a full 512G of memory, though the specs say that the TF slot only can take up to 128G.  The laptop recognizes the card and I can add/delete at will.  It charges at a reasonable rate and has a good battery charge, capable of 8-10 hours of use.  One thing I noticed and have seen on some of these reviews is that there is a perceived problem with the charging.  It should be noted that the charge port on the left side is exactly the same size as the headphone port on the right, and you can plug the charger into the headphone port and think you should be charging it, so be advised.The body of the laptop is PLASTIC, contrary to some of the Q&A discussions above.  The Chuwi has taken a major Windows 10 upgrade from Microsoft without problem (version 2004).  A dxdiag inquiry in the "run" screen" shows 64-bit Windows, Intel Celeron N4000C CPU @ 1.1Ghz (2 CPUs), 8192MB RAM, Intel UHD Graphics 600 graphics card w/4134MB display memory, Realtek audio speakers (sounds OK), Realtek microphone, Microsoft USB 2.0 camera. I'm running Firefox as my browser and Malwarebytes along with Microsoft Defender to keep the bad guys at bay.  Mousepad is big and responsive.  I've found that the lower right corner of the pad is for right-clicking.  Keyboard layout is good and is NOT backlit.I didnt find that the laptop ran particularly hot but haven't really put it through its paces, but it's not a gaming laptop for sure.  I usually have it placed on a flat surface, and it does fine and doesn't overheat.  Display is good and clear.  For the money, its a good laptop and an additional 256G of memory makes this a light-weight full Windows-supported travel companion with WiFi and bluetooth support.  Ive seen the price go up a few times, so get it while its under $300.
