Logitech G series is for serious gamers and others, like me, who understand that gaming technology, especially mechanical key switches and Hero optical mice sensors, can add a new productivity dimension to office work too.
Logitech G series Lightspeed G603 mouse and G613 keyboard thoroughly dispel the myth that wireless input devices are too slow for gaming. I venture that they are not only technically brilliant but offer more flexibility than the corded variety.
The days of dirty mouse balls, overly sensitive laser sensors and recently better optical sensors are now outclassed by Logitech’s new 4th generation Hero Sensor. In short, it uses IR LED technology via two focused lenses to deliver accurate and consistent performance across the entire DPI range, with zero smoothing, filtering or pixel rounding from 200 to 12,000 DPI. It will flawlessly track at up to 408.9 inches per second and 40G acceleration.
It is approximately three times more efficient and four times faster than a comparable optical sensor. Put another way it is ten times more sensitive than your average laser mouse. It also allows for better energy management – 500 hours of non-stop gaming (Hi mode) or up to 1400 hours business use (Lo mode) on two AA batteries.
While the mouse design favours right-handed use, it is very comfortable for a leftie too. The six programmable buttons including on-the-fly DPI shifting through up to five sensitivity settings. LGS allows configuration of macros, sequences of clicks and keystrokes to simplify in-game actions and quickly execute complex tasks. Onboard memory records the parameters for further use.
In office use (Lo) is was great – no mouse mat required even on glass – and programmable buttons allow you to assign apps to them.
In gaming mode (Hi) it was brilliantly fast bettering a Steel Series corded mouse in critical areas such as precision and response.
Logitech G series Roamer-G mechanical switches beat the hell out of membrane key switches (G613)
Until recently Cherry had the mechanical key switch market to itself making Black, Red, Blue and Brown versions (and all sorts of variations) – let me explain
- Black is a full linear 60g key press – needs more force and a full 4mm press to actuate. Great for thumping gamers and ham-fisted typists who want to press the key down fully to avoid accidental key presses. It produces an audible click.
- Red is a full linear 45g – but uses less force to get there. No tactile bump. No click.
- Brown has a two-stage 45g keypress – designed for typing and gaming with a soft tactile bump at mid-stroke meaning you only need to press half way (2mm) to activate. It is the quietest of the four types – no audible click.
- Blue has a two-stage 55g press – as per Brown (2mm), and an audible click.
Mechanical key switches are not cheap – let’s just say that the cost is around $1.50 each and you need up to 104 per keyboard hence the high cost compared to a membrane at a few cents.
Logitech claims its Roamer-G switches, developed in its lab in Lausanne Switzerland, offer 25% faster actuation than Cherry MX Brown. That is because it has a 1.5mm throw and 45g actuation pressure and as a journalist, not a gamer, it blows the MX-brown out of the water for typing speed and comfort.
They are designed for 70 million presses (MX is 50 million) and at an average of five characters per word that means 14,000,000 words or around 14,000 typical Gadget Guy articles! Considering that I used to wear out three to four membrane keyboards each year, you can see why durable and robust mechanical keyboards are so important to gamers and typists. I suspect this keyboard will outlast me!
My opinion – I think Cherry MX set the standard and Roamer-G takes that to greater heights, hell it is a quantum leap.
Lightspeed – the key to lag-free performance
Lightspeed refers to the secret “end to end” technology that gets lag – key press or mouse movement delay – to below 1ms. You need to use the supplied USB dongle and enable Lightspeed instead of Bluetooth. So far it supports the G613 keyboard and the new G603/703/903 wireless mice.
The app – Logitech Gaming Software Windows only
It is a 117.3MB download, so you expect it to do a lot – and it does.
