those more expensive boxes does still have their place, maybe little cheaper but still, they are faster, they use much better quality builds/cooling/components, I mean by only looking at the Kinhank G1 it uses basic plastic build, the inside surely uses minimum cooling/quality stuff, the Homatics Box R 4K Plus looks like better build but even that one does not come close to the Ugoos AM6B+, I have both and compared, I had to put a fan inside the Homatics to get good temps, good quality stuff does not come for free.
