I ordered 2 of these to sit on top of my telescopes running the acquisition and guiding software. Unfortunately one has an issue with the microSD card slot. The write times are unreasonably long and no other USB drive can be connected when there is a card in the slot. I have to use the C: drive to store images overnight then move the files in the morning without using a microSD card. Otherwise there are no issues with the PC.The other unit is fine. They actually work pretty well. I don't know why anyone would buy an ASI AIR when you can use one of these for less money and get the full power of a Windows 10 PC running NINA, PHD2, etc.
