Amazon.com: Razer Doubleshot PBT Keycap Upgrade Set for Mechanical & Optical Keyboards: Compatible with Standard 104/105 US and UK layouts – Razer Green : Video Games

This kit comes with everything I needed for the aforementioned Black Widow model. I bought this kit solely because of the fact that it has illuminated special characters on the number row. Why these aren’t illuminated on the included ABS keycaps is beyond me. I would say it’s a conspiracy to entice you to buy their aftermarket keycap set, except that Razer isn’t the only manufacturer that does this (My Logitech G512 is the same way)

I think I expected these caps to be somehow (more) different than the ABS caps that came with the keyboard but they seem pretty much the same. I hope that the material is more durable than ABS (as it’s rumored to be), because my WASD keys tend to get shiny after a few months of use with my other keyboards.

With that being said, these caps do have a slightly different texture to them; the difference is slight but noticeable. They also alter the way my keyboard sounds slightly when used side-by-side. I like the sound better but it’s tough to describe (heavier, denser maybe, and slightly quieter?). There are YT videos that show comparisons between them if you’re really curious.

I noticed some other people mentioned that they had trouble getting their spacebar to clear on the black widow. I don’t know exactly what model they were using but I had no trouble. One possible reason I could foresee is the orientation of the stabilizer clips on the back of the keys (see photo). The clips are not centered, and the “long side” should go toward the top of the key. Also, some of the keys on my keyboard had stabilizer bars with an indentation in them to allow clearance around the key switch, you’ll need to be careful to make sure your stabilizer bar is oriented the correct way as well.

As others have noted, the keys are dimmer on the LED shine-through. I think the reason is the double-shot molding process on these PBT caps are evidently different than with the ABS caps. If you look at the back of the caps (see photo), the translucent plastic in this key set is only in the stem and top of the key, and the ABS keys have a translucent base throughout the entire cap. There could be a manufacturing reason they are done differently, but I’m almost certain this is why the PBT caps aren’t as bright. The difference isn’t the end of the world to me. I was only operating my keyboard at 50% brightness with the ABS caps because they seemed really bright to me, and now i have to turn it higher to achieve the same level of brightness.
