I think these keys are best used on some kind of macro pad. If you were to put them on a work keyboard and start touch typing, you may not feel your way around like you would normally do with the cherry profile or an SA profile.
Really nice colors, tons of caps for the price, but like everyone else says, homing F and J are indiscernible from every other key. If you rely on tactile feedback from your homing keys, skip this set.
I have been looking for a PBT XDA set with uniform colors and this one checks all the boxes. The fonts are nice and crisp. The Novelites keys are nicely colored, not too bright and not too pale. Though since it comes in the 4 colors, you may not be able to get in a way you like.
The only complaint is the home row, the alt F and J key is very so slightly curved 'deeper' that its almost barely noticeable. I think it could have been curved deeper in to make it more noticeable.
I'm Japanese, so my sentences may be strange.
There are many types of keycaps available, so they can be used on a variety of keyboards.
I like that the surface of the keytops is rough, which makes them different from other keycaps.
First, the font choice for the lengends on these is excellent. Very smooth and crisp, though there are a few spots where the characters are slightly imprecise, (e.g. the center line on one arrow key isn't exactly in the middle of the caret, the right/left angle brackets are perfectly aligned). As others have said the color is a warmer gray than it appears in the photos, but I find that makes the legends appear sharper. They also have a very nice texture on the surface.
The only thing I don't like is the home row indents. The base set did come with alternate F & J keys, but I could barely tell a difference between them. I ended up gluing a tiny piece from a bike tire patch to add extra feedback. The patches are clear so it doesn't look too bad, but it isn't elegant.
I bought these sets because of the profile and the inclusion of odd sizes. They are great. They feel awesome to the touch and the legends look super sharp. Nice font choice, too. The colored pieces are excellent as they are not eye-piercing, but soft, almost pastel. If I had the resources, I'd buy four more sets to mod and use in my experimental builds. Great product!
