It's functional,  it's not fast and if you try doing anything other than Netflix/YouTube it gets fussy. Also, if the SSD goes out on it you're out of luck. You are not given a windows key to reinstall anything.You get told the operating system is embedded into the motherboard.  So you don't need a key because you can just reinstall from that. But there's no way to access it.But if your ssd or motherboard goes out, that means you don't have the windows key anywhere reinstall your operating system and actually use your computer again. Unless you buy another windows copy somewhere.. and since the SSD is "kingfast" which is notoriously bad for crashing, this is a problem you will run into often. So you're stuck.
