Performance is an area in which wireless mice have traditionally always fallen behind. They’re generally less responsive and more prone to latency than their cabled brethren. Fortunately, this isn’t an issue at all with the G903 for a few reasons. RFIC: Radio frequency integrated circuit transmits MCU data robustly and reliably via fine-tuned electrical pathways.
MCU: Microcontroller unit translates data from the SPI, via enhanced firmware, faster than ever before. To many, this peripheral might seem like a premature sequel. However, its ability to constantly draw power from Logitech’s new PowerPlay mouse pad could solve one of the last annoyances of wireless gaming mice. MCU: Microcontroller unit translates data from the processor, via enhanced firmware, faster than ever before. First is its use of the PMW3366 optical sensor. This isn’t a unique feature, but the sensor is one of the best on the market and means the G903 has a fantastic 200-12,000DPI sensitivity range.TIP: We recommend using the cable and adapter when you’re in wireless mode. This allows for better connectivity and easy access to the cable when you need to recharge. Second, and more importantly, is the G903’s use of Logitech’s stellar Lightspeed wireless connectivity. Lightspeed is a custom tech designed to offer gamers an insane and unnoticeable 1ms response rate. It’s worked a treat on past products such as the stellar Logitech G613 wireless keyboard, and this remains the case here. Logitech G engineers worked through a complete end-to-end technology optimization from sensor to firmware, circuitry to antenna. We tested and refined each component, focusing on the slowest link until nothing was slow.
Up top you’ll find basic buttons to adjust the G903’s DPI, and switch between a smooth or step action on its wheel, plus the usual left and right controls. Outside of this, the only difference between it and some of Logitech’s cheaper offerings is that the G903 has local memory that lets you save up to five different profiles on the mouse. You can toggle through the various presets manually using a button on the bottom of the mouse. At the end of the day, I think that the Logitech G502 Lightspeed will be the better choice for most people looking for a high-end wireless gaming mouse. It's true that you have to pay more for it, but the increased optical sensor accuracy, higher DPI range, and more extensive weight-tuning options will very much come in handy if you're looking to take your gaming experience to the next level. The bigger battery life is great, too, as you won't need to worry about charging it very much. That said, as convenient as the PowerPlay is, it isn’t going to get the Logitech G903 fully charged in a jiffy. Going from 0% battery to a full charge with your mouse on the PowerPlay would take between 12 and 14 hours, by Logitech’s estimate. Designed with the world’s leading pros. Engineered for pure performance and nothing in the way of winning.The Logitech G903 might be a wireless gaming mouse, but it feels as seamless as a wired one. That’s no small feat, and that’s all thanks to the same Lightspeed Wireless technology that was also in the G900. We never experienced any latency or loss if signal despite using the peripheral in an office saturated with Wi-Fi, Bluetooth and every other type of wireless signal. MCU: Bộ vi xử lý chuyển dữ liệu từ SPI, thông qua phần sụn nâng cấp, nhanh hơn trước đây rất nhiều. THE WORLD'S BEST SELLING GAMING GEAR Based on independent aggregated sales data (FEB ‘19 - FEB’20) of Gaming Keyboard, Mice, & PC Headset in units from: US, CA, CN, JP, KR, TW, TH, ID, DE, FR, RU, UK, SE, TR Some will argue that optical sensors are better than five-year-old laser technology, meanwhile, on paper Razer has a leg up on the sensitivity department. Ultimately, though, after using both mice for a week at the same time, we can confidently say they’re both equally as accurate and reliable. Get ready for endless gameplay. The POWERPLAY wireless charging system keeps G903 and other compatible G mice charged while at rest and at play.* Just attach the included POWERCORE replacing the optional 10 g weight and cover. Never worry about battery life again.
Starting with the basics, the G903 comes with up to 11 keys, depending on how you set it up. Out of the box, there are two extras on its left side and an option to add two more to the right using a magnetically attached plastic plug. RF antenna is designed specifically for LIGHTSPEED for absolute minimum impedance and maximum signal strength.

The idea here is to let gamers set up the mouse for either their left or right hand – which, as a lefty myself, is very welcome indeed. You may even choose to go all-out, and have four side buttons – although, personally, I think that’s overkill, even if you’re an avid MOBA or ARPG player. The mouse can also be connected to your computer using the supplied USB charging cable. Your mouse works in data-over-cable mode when it’s plugged into the computer. This connection also charges the battery.
