The answer is YES - this is a legit Windows 10 Pro PC for $100-something dollars.  And YES it does work well given the price point... a family member of mine has a PC that is about 7 years old and this thing blows it away in terms of speed and reliability.  That's because this thing is completely solid state - no moving parts whatsoever.If you're going to buy this I suggest you be a PC/Windows power-user, or have access to a Windows power-user... because it can be quirky to set-up and maintain.  For example... when you have to reboot (and you will) the system can hang.  It's an easy fix to boot (remove the HDMI monitor cable, and/or the dongle for your keyboard/mouse and it will boot) but you can't expect Grandma to do that every time the system requires a restart.Strengths... it's tiny and super light in weight.  You could attach this to the back of a TV (bracket included) or hide it almost anywhere.  It's 100% quiet (no moving parts).It runs very well for regular tasks (perfect for youtube, streaming HD video, browsing the web, word processing, simple games etc).  I'm using it as client for my media server so I can watch any of my HD content on my bedroom tv.  It however has its limitations... NO, you won't be able to run newer 3D games or 4k video or other high-end tasks without any issues... this is a basic Windows 10 PC, not a power-PC, don't buy it expecting it to be anything more than basic.Cons:-Runs warm... the outer box is always warm to the touch, especially when the CPU is being taxed.  That's to be expected because there are no fans, but the longevity of the product concerns me because of this.-Quirky... as mentioned above, you need to have some basic PC and Windows knowledge to own this because it tends not to be "plug and play".  Yes, they offer advice and help via their online forums, but to be honest they default to that way too much ("Check the forums... ask on the forums").  There really should be a standard FAQ or User's Manual you can reference, you shouldn't have to rely on asking questions online to get answers to basic operations problems or questions.-Storage... with a low volume solid-state system drive, you're going to want to invest in a decent sized SD card (supports up to 128GB) to store files on.-Sleep... mine will sleep if I tell it to sleep, but will NOT enter sleep mode on its own (I set the power options to sleep after 30 mins).  They tell you on their forums not to worry about sleep mode because "this PC consumes a very little amount of energy" but that's nonsense to me, any PC should sleep or be shutdown when not in use, no matter how little energy it consumes when its turned on.  I'll be adding a media remote to this PC so I can manually tell this item to sleep and wake-up, because something in this set-up is preventing it from sleeping when it's automatically supposed to.Other concerns I've read:"Don't let windows update itself" - I didn't find this to be true... when Windows 10 updates itself and needs to reboot you may need to pull your monitor cable and keyboard dongle out to get it to boot, but it accepts all the Windows updates (so far).-"It's not a full copy of Windows 10" - well yes and no it isn't... you don't get a disk and registration key with this PC to use wherever you please... but the copy of Windows 10 Pro that is installed on this PC is indeed FULL and LEGIT and AUTHORIZED.  If you need to start clean their forums will direct you to the software and provide you with a registration key... but this copy of Windows 10 is tied to this PC.  So no, you don't get a full copy of Windows 10 to use however or wherever you please, but yes, the copy of Windows 10 installed on this PC is FULL and AUTHORIZED.I am very happy with my purchase so far, and think if you know your way around a PC and Windows and can deal with a few quirks here and there, that you will be happy with purchasing this as well... especially at this price.3/2021 Update, after one year of use:  going stronger than when I got it.  Still has accepted every single update Microsoft has thrown at it.  They sometimes take a little while to process, but no update has “broken” my system.  In fact an update about 8 months ago somehow fixed the reboot problem where you had to remove the monitor cable.  It now reboots every time like a champ without having to pull any cables.  Runs/streams kodi 19 and 1080p content to my bedroom tv a few hours a week and works better than when i bought it.
