I have a Keychron k2 with the German layout and the PBT Retro caps with Blue switches and I am more than happy with it. Very lightweight and portable and the 3 Bluetooth slots are handy. I know it’s not the best one out there but it gets the job done pretty well.
I will do foam padding and o rings in the future to reduce the hollow sound and the bottoming out of the keys. I dont low well the other keyboards are made in this regard.
You will eventually need a wrist rest with the keychrons due to their height. Also the battery life is not as great as it could be. I am most of the time directly connected to my MacBook so I won’t notice this much but I know that the battery lasts around 1-2 days of work depending on the type of lighting you choose.
Hope that helps somehow.
K2 is very lightweight imo. And it fits easily in all my bags.
