ZSA Moonlander is an easy avoid. They have a defect on their thumb cluster, the plastic that holds them to the main board is thin and breaks after a few years of use. Good thing they sell spares so they can be easily repaired but bad thing is trying to order them. They don't want just any one buying parts and even sending a photo proof you own a broken Moonlander is not acceptable, they want a receipt of the original purchase or they refuse to sell them.
