Colors: FRICKEN BEAUTIFUL! They look like skittles!
Font on Keycaps: Too big for my taste. Looks a bit kidlike - double the size of the normal font (normal Ducky size is half a cm)
Keycap Size: Too large/1.5 CM - normal Ducky size is 1 CM

TLDR: Love the colors but the font is too large and the keycap size is an awkward height which makes it hard to mix and match keycaps.

Warning.

Short shift is a 2 unit, not 1.75 like used on every other 65% board.

Nice set, but is now useless to me and not worth returning.

These are beautiful, high-quality keycaps. The colors are saturated and they're stunning to see in person. Product itself is 5 stars.

Personal usage opinion is 1 star. They're not for me. I have smaller hands and I didn't think the SA profile was going to be as large as it was. My hands cramped up less than five minutes into typing. I'm sad because they made my board look nice, but I either need larger hands or longer fingers to comfortably type on this product.

Ordered the Ducky Afterglow SA keycaps on Tuesday, and it arrived the next Monday using international express shipping to The Netherlands / Europe. These keycaps looks great, the quality is as expected from Ducky / double shot ABS keycaps. Some key wobble is introduced due to the SA profile, where the OEM profile doesn't wobble as much. However, it's definitly not annoying and the wobble is well in range for what is considered acceptable wobble. These caps look amazing, especially with blue purplish backplate of my Ducky One 2 Horizon TKL.

I have these on the Ducky One2SF and they look very boss. The set comes with the smaller shift alt fn keys for the SF board. No shine-through, however the board still has a great glow underneath. I was planning on using the board without the rgb lighting but it actually looks nice. I had those TFUE key caps and the light still bled-through to where you could see the stem. Very ugly with the backlight.
