These keycaps are great quality. I also have 2 ABS MT3 sets, I like them, but they are a bit smooth after a lot of use. I love the texture that this PBT Operator set has.
These feel great, sound great, and look great!
I love the font, and all the extra symbols for other board layouts. The symbols for non-alphanumeric keys are also fun. It's nice to get some color alternatives for shift keys (lighter blue) and function keys (purple). Some built-in highlights if ye want.
Neater packaging. I've seen nice trays from other keycap sets here where each key is secured in a particular place. The packing here was loose rows of keys touching each other. It's very easy to jostle and get keys jumbled up within their rows. Mine arrived a bit jumbled.
One more unique symbol or an F13 key for row 0. I know this is not very standard, but my only options for my F13 key were repeat symbols.
The set is a pretty basic, simple colour scheme that adds a slight splash of colour to it with the blue Shift and purple Fn. Personally I rather have the accent colour key be Enter, but its a unique placement that just seem to work with this set.
The sub-legends in the number row for the function row keys along with the special characters is a nice addition. Should be useful if I ever move into <60% layouts.
However, compared to my double-shot sets, the dye-sub legends does look a little fainted. It is expected with dye-sub, and I can't really tell when using it day to day. That said, I like the rougher surface with PBT and time will tell if the legends fades or if the keycaps starts to shine.
