Not bad if you don't look close.
I was very excited to receive these, as they were an affordable set of green keycaps that were backlight compatible, a rarity as far as I've seen. However upon receiving them, I was let down.
The legends on the green caps are blurry to the point it looks like I need glasses, but the white keycap legends are crisp and clear. I retained hope that they would look better with backlighting, but unfortunately upon getting the caps set up on my board I was let down again. The backlight shines through all of them unevenly, and has visible lines in some sections (most notably the A key).
The woes don't stop there, as several of the keycaps came with scratches on their faces.
Perhaps the biggest tell of the quality put into these keycaps, even the "Tai-Hao" advertising keycap has a massive bubble in it's face.
Overall, severely disappointed in these caps.

Notes: This is purely a standard layout only set. There are no alternate key sizes, so be aware of that.
For some reason I received a green, rubberized 7 key. I'm not sure if this is intended to be included, as it doesn't appear in any of the photos.
