I love the feel of KAT profile keys and the smooth texture of these keycaps is awesome. The kit is generally pretty expansive and one of the few that includes macOS legends, but unfortunately it's missing a few key pieces to make certain layouts viable. There is a single esc key for Row 5, but two separate row 4 ~ caps, so I wasn't able to have an esc legend on a 65% build. Also, there is no 1u Command keycap, so I could not fit one to the right of my spacebar for the KBDF67 r2 layout. The options for the far right column of navigation keys is also slightly limited.
All in all, it's a very nice quality set of keycaps for the price, and I'd be 100% satisfied if there was only a row 4 escape key.
