This is the best "stick" pc that I have tried.... the wifi antenna makes a world of difference for the connection, and the bluetooth comes up quickly..  it upgraded to Win10 without any issues(I used a usb mounted version to save time of downloading) and runs all(so far) Windows application that I have loaded, including QuickBooks, which is a cpu/memory hog...  The best thing about this product is the tech support.... via email they respond rapidily and answer the questions straight forward..  I am using this on my Home Entertainment Center as a pc, and will probably expand it's function to include Kodi....  it accepted a 64mb MicroSD with no issues, and I will probably leave that in as an additional SSD... I purchased a HDMI extension(1ft) due to the location of my port and it is wort it to buy that outright with this unit...
