I have 2 GMKtec PCs ~ Very Satisfied!
I have 2 GMKtec PCs. One is a NucBox3 that I've had over 2 years. It's been very reliable. It is running Win11 Pro and I use it to run Blue Iris, the opens source DVR program that runs my 4 cameras for home security. It runs 7 x 24 and I've never had a problem with the machine. The 2nd machine is a NucBox K7 that I use as my home office PC. Also Win11 Pro, Office 365, Zoom, Google Drive, DropBox, etc. It performs really well and also without any problems. I am a Microsoft Insider, so I'm usually running the latest Windows release candidate. I have found customer support to be responsive. It's important to communicate clearly and factually. This helps to mitigate any issues of international communication. It's necessary to communicate about bios and driver updates for GMKtec specific firmware. In my experience, GMKtec produces a high quality, good performing product and supports it adequately well.
