The caps feel great. My problem is the shine thru. If you have SMD LEDs, don't bother with these keycaps. If your keyboard uses SMD LEDs the legend is only really half lit, and it is even worse if you use non-translucent o-rings. Things are much better if you keyboard has the LEDs on top of the switch. The bottom gets noticeably dimmer, but at least the entire legend has some glow, unlike with SMDs.

For what it's priced at you get what you pay for.
The PBT feel is nice, but the PBT texture is inconsistent with a few keys. Some are smoother than others.

Backlighting on the main characters is highly visible but the rest of the keys are VERY spotty.
The main number row and F1-F12 keys being the worst offenders.

If you're okay with these problems it's not bad at all. I chose this keycap set for the font and I wasn't disappointed there.
