Pros:
- Switch snaps in very tightly. No chance it's gonna come out accidentally. Good tolerances!
- Frosted case acts as a light defuser, and does it well. Looks good, and uses good quality materials.
- Multiple modes to play with.
- Reasonably priced. They're not overcharging like they could since it's a pretty niche product.
- It's glow-in-the-dark! I didn't see it listed anywhere, but it glows in the dark after being exposed to bright light.

Cons:
- Actual lighting modes don't seem to match the listed ones on the site. It's close but you really gotta figure them out yourself.
- There is no "hold for RGB cycle, release to turn off" mode. That's the only edge the Razer ones holds over this one. You either have to keep tapping for light, or have it in the mode where it runs constantly until you switch modes to turn it off.
- Cheap lanyard will absolutely break during normal use, and could cause you to lose it. Must upgrade the lanyard to be a usable keychain. Replaced mine with a little metal one. Both are shown in pictures.
- Shipping takes a month, but that's fairly normal for every China-based site I've been to.
