Logitech G603 Review

Logitech G603 Review

The Swiss company Logitech is renowned for providing very good quality peripherals. In this article, we’re going to test and give our opinion on one of the best wireless gaming mice: Logitech G603 Lightspeed. With this very aggressive price, what about performance?

Getting to know the Logitech G603 Lightspeed mouse

Let’s start our test with the usual unboxing. In the package, we have the mouse, the 2 LR6 AA batteries, the lightspeed receiver, an extension cable for the receiver, a user manual and warranty and certification notes. The Logitech G603 Lightspeed mouse measures 43 x 68 x 124 millimetres for 90 grams.

This is a wireless optical Logitech mouse in black and grey colour with a silver Logitech logo positioned on top. It is equipped with Lightspeed technology, a stable and fast technology developed by Logitech. You can connect it to your computer via Lightspeed connectivity or from the Bluetooth connection. This mouse is compatible with different platforms such as Windows, macOS, Android etc.

The G603 looks like the G403 Prodigy Wireless and G703 mice, but it has 2 batteries, not a battery. The G603 is, therefore, cheaper and more accessible. At first glance, we have no complaints about the finish of the G603. She is well-groomed on all lines.

The mouse has 6 programmable buttons. A button located above the dial allows you to change the sensitivity on the fly. Here you can choose directly from the 5 sensitivity levels. If you want to program macros and want to save them, you can make the settings in the Assistant software for video games from Logitech. This mouse has no backlight but instead incorporates a Gamer HERO sensor, known for its performance reaching 10 times more precision.

At the click level, the buttons offer straightforward, flawless clicks. The quality of the Omron D2FC-F-7N used is no longer to be proven. Logitech has promised more than 20 million clicks on each button. The wheel allows easy scrolling. On the other hand, it does not have a fast scrolling mode with disengagement or horizontal scrolling.

If you want a mouse with a fast scrolling system that disengages automatically, you can go for the Logitech MX Master 3 Advanced mouse . The latter is indeed equipped with Smartshift, a system that detects whether you want to switch to fast scrolling. In this case, you can have scrolling at more than 1000 lines per second.

Very useful if you are dealing with documents with several pages or a spreadsheet with thousands of lines. The G603 Lightspeed mouse nevertheless offers good performance and features a 32 bit ARM microprocessor. It has a 2-year manufacturer’s warranty.

Configurations of the Logitech G603 Lightspeed Mouse

The Lightspeed technology was implemented by the Swiss company Logitech to eliminate all the problems with wireless connectivity. The lightspeed connection is thus as stable as a wired connection. Everything has been studied by Logitech engineers, including all the electrical circuits, the antenna and the firmware. Nothing has been left to chance in order to eliminate any latency.

The Gamer HERO (High-Efficiency Rated Optical) sensor allows for its precision without smoothing, acceleration or filtering from 200 to 12,000 DPI. It allows having a performance 10 times more than the previous generation mouse sensors (PMW3366). Hero technology thus becomes the new standard in sensing technology, as it provides a revolutionary perf-power ratio in the world of wireless technology.

This sensor incorporates an intelligent power management system that adjusts the refresh of the image in relation to the movements of the mouse. Electricity consumption is thus well managed. The Hero sensor remains precise and responsive even to images scrolling over 400 FPS.

The Logitech G603 mouse provides advanced power management based on mouse usage. Below the mouse, you can find a switch to toggle the power mode from Lo to Hi. With Hi mode, the G603 offers a 1ms report rate with over 500 hours of battery life. It should be noted that the G603 thus offers twice as much autonomy as the previous generation mice. With Hi mode, the mouse prioritizes performance.

This mode is recommended during gaming sessions. When you’re not playing, you can switch the mode to Lo for more battery life. With Lo mode, the report rate is 8 ms with 18 months of battery life. Lo mode corresponds to office use with a refresh rate of 125 Hz.

To replace the LR6 AA batteries, simply lift the central cover under which the 2 batteries are housed. The clip is magnetic and therefore easy to undo. We had a concern about the mounting stability of this magnetically attached hood, but after hours of testing, we didn’t experience any issues.

With Assistant software for video games, you can customize buttons and assign macros. You can also modify the settings saved in the internal memory of the mouse.

The software is very intuitive and easy to use. With the latter, we can therefore associate actions with additional mouse buttons. This offers an undeniable advantage during gaming sessions because we can configure our essential movements within reach of a single click: building, crouching, rushing through the crowd, healing injuries, etc. This software also gives you a heat map, reporting which buttons you will use the most.

On the design side, with its curved shape, the mouse fits perfectly into the palm of the hand. We regret a little the absence of non-slip materials on the side. The hand tends to slide a bit on the G603, especially when we want to lift the mouse. That doesn’t bother you too much, but if you want a mouse with a better grip, you can go for the Logitech G403 or the G703. The G603 glides perfectly on its two long PTFE pads. The manufacturer has a service life of around 250 km.

The G603 Lightspeed mouse was presented by Logitech with the G613 keyboard which also offers good gaming performance. So you can use this keyboard or opt for others such as the Logitech G915 Gaming Tastatur or the Logitech G513 Carbon Lightsync keyboard with backlighting. If you want to experiment with using a vertical mouse, the Logitech MX Vertical Wireless Mouse will do the trick. Looking for a keyboard that directly integrates a mouse next to it? We recommend the Logitech K400 Plus keyboard.
