I purchased this device almost 2 years ago, it is as advertised. It is built well, compact, quiet and stable.  I recently had a hardware failure, I contacted Kingdel and they had me try a few things, still didn't work.  They had me ship it back to them (my cost) and they repaired it and shipped it back (their cost) the repaired unit with fully updated Windows 11.  This is the best PC of this format I have used, I use them for clients, I will continue to use their products and recommend that you do too.
