Logitech G910 Orion Spark, to give it its full name, is designed to give the sensation of premium packaging, despite not having any added accessories, or shiny stickers. It does so by having a thick black inner-box with a cut-out of the Logitech gaming logo on a blue-layer "background". Inside, you get the mech, an alternate detachable wrist-rest and a short (for Logitech at least) multi-language Set-up Guide.
Unlike most mechanical switch-types on the market right now, Logitech's G910 ROMER-G is of only color and design, and that single one is similar to Cherry's MX Brown. While the feel is similar, the architecture is wildly different. The switch is split between the following individual parts: spring, dual contacts for actuation, and a landing pad to soften the bottoming out noise of the key-press. The specs reveal ROMER-G is weighted at 45g, with an actuation point of 1.5mm, lower than that of a traditional Cherry's MX switch.
Backlighting is integrated in the switch, via the a so-called light pipe leading up to a surface mounted LED right in the center of the switch. The design is said to focus light evenly and throughout the legend, and minimize leakage. This means the light won't burn your eyes like the one on Razer's BlackWidow Chroma, but manage to keep an even lighting pattern across its surface.
The switch has also been rated at 70-million keystrokes, making ROMER-G the highest-rated keyboard switch in production.
The company is calling its custom shaped and colored keys "Performance Facet" caps, and actually has a patent-pending for them. That being said, I do not like them that much. The assymetric design should theoretically keep the fingers centered and improve edge-strike activation. However, after using the G910 for several months, I didn't find that to be the case.
I am used to them now, but when I first started using this keyboard, the caps were fighting me. At times, I find my fingers slipping because I didn't press a key dead-center. The edges are sharp and tall, with angular slopes, and that's what actually causes the discomfort. If the edges were smaller, or the shape was curved instead of edged, then I probably wouldn't have had these issues with it.
Eventually, you become proficient with the keyboard (I know I have), but when I returned to other mechanicals, like Razer's Blackwidow Chroma, I discovered I was actually typing faster than usual. Yes, in a way, G910's keycaps did improve my performance, just that it happened on other keyboards.
I am quite fond of Logitech's layout choice. For the most part, the mech uses a standard ANSI layout, with several additional macro keys: a row to the left-side, and one atop right above F1 through F4.
There are no custom-shaped keys to screw up the layout, but since ROMER-G uses a custom stem, that wouldn't matter anyway.
Multimedia and backlighting
Taking a few lessons from its older sibling the G710+, G910 features dedicated media-keys and Profile buttons. Right above the Numpad, you have the volume rocker & mute button, media controls, lighting on/off and a Windows lock button. The lighting for these buttons as well as the three Lock indicators (Num, Caps, Scroll) is blue-only and cannot be customized like the rest of the mech.
The surface-mounted LEDs are able to provide 16.8 million color backlighting in a varied number of customizable profiles. The lighting is uniform across the board with little to no light leakage. It might not seem as bright as Razer's Blackwidow Chroma, but it is far more consistent.
G910 comes with two slightly different assymetrical plastic wrist-rests. They both angle from the edge to support the hand in an ergonomic position, more for the left than for the right, of-course.
The rests are clipped on the top side of the keyboard frame, which extends from the mech. The overall shape means you won't be able to use any other wrist-rests except the ones included in the package.
This is slightly unfortunate since the overall assymetrical shape of the rest is not really comfortable for typing, for example.
Right atop the keyboard, there is a small blue pull-out stand for a smartphone. The dock is passive and features no direct connectivity for whatever device you decide to position.
To accompany the tray, Logitech has released the Arx Control mobile app, which allows the mobile device to communicate with the PC and respectively the Logitech Gaming Software via Wi-Fi, and act as an added display.
Arx Dock accomodates devices of a thickness of about 3-cm.
The G910 has a thick, somewhat stiff, 1.8meter long rubber cable terminating in a single gold-plated USB plug. Orion Spark drawsenough power from a single USB, and features no additional hubs to multiply connectors.
