“I realy like this keyboard. I feel is harder to make typos compared to the K3 v2. I decided to go with the K1 Pro instead of the K3 Pro and it's going to to take time to adjust to the new layout, but the feeling and shape of the keys is definitely better.”

“I had a full-size mechanical keyboard before that was tking too much of deskspace. This keyboard with it's 65% size is amazing and saves quite some desk space.”

Keychron K1 Pro vs K3 V2: your questions

The K1 Pro comes with double-shot PBT keycaps, which are durable and resistant to oil and shine. The K3 V2 comes with ABS keycaps, which are lighter but may wear down faster over time with heavy use.
