The Logitech G series has always been a good line in the way of PC gaming. The G703 offers a way to keep your battle station crisp and clean via a wireless mouse all without losing any of that input time. With added addition of lightspeed Logitech is claiming a 1ms input lag. Hopefully this review will help to clear the air as to rather or not this may be the right set up for you. First off let me talk about what you can expect to see right out of the box. You will receive the wireless mouse, usb adapter, wireless receiver, 10g weight and the braided micro usb cable which is necessary for lightspeed mode to be engaged. First impressions of the mouse is that it appears like a ordinary mouse. Its very simplistic but at the same time very clean looking. It comes with 6 programmable buttons and adjustable RGB lighting for the logo and scroll wheel. Logitech provides a free app to download to your PC which allows for pretty decent customization. I won't go in to full detail of the apps function but expect to see such functions as RGB controls, button mapping, DPI customization, Macro set up and much more. There are a few gaming pre-sets built in to the app such as League of Legions mapping. The top button button on the mouse near the scroll wheel can be customized but comes set as your DPI adjustment. There are four preset adjustments which are as follows 400,800,1600 and for the quick response 3200. DPI settings can be changed through the app to fit your play style so don't think that these settings are fixed as they are not. For those new to gaming DPI in a simple form is basically mouse senstivity or speed. The higher the number the faster or more response your mouse will be. Logitech also provided a 10 gram weight which can be added to the mouse to give it a more weighted feel as well. Lets talk about its main purpose which is gaming and its wireless function and stability. The two main games that i like playing are mmo's and loot shooters. In the way of mmo's mouse speed is very critical to me as im constantly switching between targets and my utilities. The added side button mapping helps take the load of having unmapped utilies that i can now use in conjunction with the ability to adjust my DPI on the fly given my current situation. For example if im grinding for materials then i turn my DPI down as its not really necessary for such quick response however when its time for me to run a raid i'll crank my DPI up to max and utilize my mouse button mapping to access my utility skills. When it comes to loot shooters such as The Division 2 i expect very quick response times with quick access to my utilities such as flash bangs and grenades. Being a wireless mouse my biggest concern has always been response time and the bluetooth being interrupted by all my other wireless sets up that i have. I have to say im greatly impressed and never once experienced any issues or lag. Even with lightspeed engage i honestly did not notice any difference between input lag. If it did improve anything, it wasn't enough for me to even notice. The scroll wheel feels very nice and responsive to the touch. What i really like was each scroll of the wheel felt firm but yet smooth and each indentation gave it a better feel and pinpoint accuracy in my opinion. It helped to eliminate any over or under scrolling for whatever function you may have set up for it. Here's the bottom line. This set up is perfect for anyone looking to save some money or get in to key and mouse PC gaming. The fact that you only have 6 keys to map means that the mouse will not become too overwhelming to set up for new gamers. More experienced gamers may want to opt out for the 9 series for the added button mapping available to the mouse. For me this is actually a perfect fit for me as l like to switch between mouse and keys to a Astro gaming wireless controller. The buttons are smooth and very responsive and the added app that is provided allows for some pretty good deep customization. The mouse is light weight and is built to be ergonomic to fit comfortably in your hand. Unless your looking for more button mapping this mouse is sure to please just about everyone out there.
