I purchased two of the black Hackberry Pi CM5 Q20 units from Elecrow. They have been delightful to setup and use. I even got Ubuntu running on one of mine. Unfortunately my units had a minor flaw with the left speaker that meant I needed to contact Elecrow for support. Elecrow was very responsive and came up with a solution to ship me replacement parts for the left speaker on my two units. A+++ support I really appreciate your hard work. I would recommend anyone looking for a Hackberry Pi CM5 purchase one. I think you'll be pleasantly surprised. After using mine for a couple weeks, I bought a third blue one (Pictured). Oops! I might have a Hackberry problem :D
