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.
