Topre Realforce 104UB vs Azio Backlit Mechanical Gaming Keyboard

Topre switches are a mix between mechanical switches and rubber dome switches. They have mechanical components, however they are covered beneath a rubber dome which protects the switch. They bring a mechanical feel, and mix it with the durability of a rubber dome switch.

Variable weights under each specific groups of keys was done in a bid to prevent RSI (repetitive strain injury). For instance, the groups of keys that the pinky finger hits are much lighter/softer than the rest of the groups of keys that are pressed by the rest of the fingers. Variable weights are achieved by having either heavier or lighter rubber domes. Whilst this idea is very useful for normal typing, for gaming it's not so great: for instance, when dealing with First Person Shooter games that requires WASD keys, those sets of keys feel very light when fingers other than the pinky are used to actuate them.

Silenced Topre switches are designed for those who do not particularly like the sound of keyboards being tapped on or for those who may be concern over disturbing others when using a noisy keyboard. Silencing is done mainly by placing a material that absorbs the sound of the slider when it makes contact with the slider housing. This thereby prevents excessive noise when the key has been released after it has been actuated. The overall effect of a silenced Topre is quite astounding as it may give the impression one is on a cheap keyboard (obviously, the reality is actually the opposite).

PBT (polybutylene terephthalate) keycaps last longer than other keycap materials, and are more durable. They are more expensive than ABS (acrylonitrile butadiene styrene), which is why they are less commonly found.

While the RGB model costs $80, it provides full per-key RGB lighting complete with different effects. While this doesn't offer any extra functionality, it adds some flashiness to your build.

The base model of the keyboard offers a white backlight (no RGB), and the brightness of the backlight can be adjusted to suit the ambient lighting.

There are two switches to choose from: Kailh blue or Kailh brown. The blue switches offer a bump at the activation point as well as a click, while the brown switches offer a bump without the click. These switches are slightly heavier than the corresponding Cherry MX switches, but are similar in the way they act.

The bezels of the keyboard are small, and the design of the board is minimal instead of gaudy gamer-focused designs. It has a volume roller in the top right accompanied by the mute button which makes the board feel more premium than it's price point would suggest.

The keys also appear to be floating - while most keyboards have their keys recessed behind the casing, these ones aren't. this leaves their side exposed, and makes for a more unique design than other boards.
