Once in a while we will check out Logitech to see what is going on and if they have come up with new gadgets to interface with the computers and notebooks. Recently, we happen to spot new series of Logitech wireless gaming mouse, and began to take a quick look at what the new design has to offer. Having used the G502 Proteus Core and G600 MMO mouse, both of which are wired mouse with good design. We are eager to see what the most innovative computer accessory company in the world has lined up in the new offering.
Traditionally, a gaming mouse is designed with a wired connection to ensure quick response and a minimal lag between the user and the computer. Apparently, the new series introduced a switch from wired to wireless while promising high speed, lag-free connectivity. Logitech gave the new technology the name LIGHTSPEED with a response time of 1ms, using a highly optimised 2.4GHz wireless connection. What this means is that every click and movement of the mouse is supposed to be nearly instantaneous.

It seems that not all the previous versions have the new upgrades, but only the top of the line G903, G603, G403 and a new G703. There are no new versions of the G502, and both G502 Core and G502 Spectrum appears to have quite similar specifications except for that the latter has programmable RGB lighting. So if you are looking at new gaming mouse with plenty of buttons like the G502 or G600 MMO mouse, the only option is the G903. Due to this, we are not quite keen with the new series even though there is an upgrade to the wireless technology, meaning that we are not going to rush out now and grab one of this new mouse. The new design would probably entice hardcore gamers or those who are looking at pro-grade wireless gaming mouse.
However, we noticed the implementation of the wireless charging for the G903 might be an indication of what is to come in future. All of the mouse using the new Lightspeed technology have a very short battery life of 32 hours or less. To stay wireless, it makes sense to have wireless charging coupled with the advanced and fast but power-hungry LIGHTSPEED wireless. Of course, this would come at a premium price as it is only available for the G903.
Our brief review is based purely based on the interpretation of the specifications provided at Logitech website, and below is a comparison table of the Gxx3 models.
