Same for me. The Galago Pro (galp5) is quite ok but the firmware has bugs and they are not fixing them. Over the last 2 years I have had the fan running constantly when a USB-C device was connected, the fan going into full turbo mode over night, the screen started to flicker after wakeup on battery and some other issues. And battery life is beyond terrible.

After two years of struggle I have thrown the towel and got a used Macbook for the same price. I am starting to question their engineering priorities. Instead of developing new desktop environments I think they should make sure their devices are rock solid and work perfectly with Linux. That's their USP and they are not delivering on that promise.
