Unique Stealth Design: As the first ever pudding keycaps to feature blacked-out, legendless tops, they give your keyboard an incredibly sleek and clean feel when its RGB is off—a must-have look for truly minimalist setups
Translucent Sides: Designed to let more light through, the frosted walls on these ABS pudding keycaps bring out the full brilliance of Razer Chroma RGB in every direction
Bottom-Lasered Legends: Unlike regular keycaps which are lasered from the top, this method ensures legends that won’t wear off and shine brighter thanks to a thinner layer between the keycap and light source
Keycap Removal Tool & Stabilizers: Specifically designed for Razer keycaps and switches, the set includes all the tools and parts you need to conveniently upgrade our optical and mechanical keyboards
Universal Compatibility: The set works with all our Mini, Tenkeyless (TKL), and full-sized mechanical/optical keyboards, and consists of 128 keycaps that fit with Razer and standard 104/105 key US and UK layouts
Unlike most controllers, you can vary not just the startup pressure (which is what most other units do), but also the ongoing, running pressure output.
The controller is also much smarter than most of the slightly cheaper ones- it doesn't just give up for 24 hours if it gets no flow,for example, as some others do. For an extra 10% or 20% on the price, it's well worth the money to get a
much smarter product, that's clearly had a lot of thought go into the software.
The instructions, translated from Italian, are not the clearest, though.
