Keychron has a bit of history for bad QA for some batches. Quite of number of users have their keychron faulty after 1-2 yr of use. THere are complain after service as well, almost zero support. If you tio the good batch, you heng.
Aesthetic wise, very nice as they are using higher profile keycaps (OEM keycaps). Their color matching for their keyboard based and keycaps is one of the best imo. Sound profile wise, they required modding to attain a decent sound, unlike its competitors, which ready made and the sound is good.
The price is not the friendliest. They are quite expensive, considering them being a china brand.
What you looking is 75% keyboard. Maybe u can look at other brand w aluminum base like Rainy75, Hi75, Bridge75, Monka A75, Fury75 or SKN青鳥75(their own sister brand which is now more popular now in China than keychron). Of course there are others but certainly more worth than Q1 imo.
