Logitech G403 Overview

The Logitech G403 Wireless Mouse is a high-performance wireless mouse that is a very popular option among gamers who want to be able to switch between both wired and wireless connections. It has an all-black design with fully customizable RGB lighting accents in both the G logo and the scroll wheel.

G403: Wired + Wireless Connection

The G403 has a built-in rechargeable battery that charges any time the mouse is plugged in through the included USB to micro-USB cable. The G403's wired USB connection gives you the option to plug in directly to any computer without having to worry about switching over the wireless USB dongle adapter.

G403: Battery Life

You can expect about 20 hours of wireless use before you'll need to recharge. The Logitech Options software will notify you when you hit about 20% battery remaining so you can avoid running out of battery during important moments.

G403: Weight

The G403 comes with a removable 10 gram weight (pictured below) that magnetically clips into place on the bottom of the mouse so you can switch between 97 grams for a lighter mouse and 107 grams for those who prefer a heavier mouse.

G403: Tracking Resolution

The G403's tracking resolution can be set between 200 and 12,000 dpi, which is easily a broad enough sensitivity range for any potential uses you may have.

G403: Who Should Buy the Logitech G403?

The Logitech G403 is a suitable mouse, and an excellent choice, for the vast majority of users looking for a high-performance wireless mouse. If you want customizable RGB lighting, a built-in rechargeable battery, and no AA battery hassle then go for the G403.

G403: Personal Experience

The Logitech G403 has been my daily driver for the past 2 years, and I would confidently recommend it to anyone in the market for a wireless mouse, that being said, it is becoming more difficult to find each year with its production being replaced by the G703.

The scroll wheel is super smooth, there are 4 programmable buttons (not counting the left and right-click buttons), and the overall feel of the hardware quality is very premium. At the end of the day, it's a snappy, high-quality mouse that has lasted me over 2 years with no issues whatsoever.

Also, if you're into it, there are some really cool RGB customization features using the free Logitech G Hub software including making the RGB lights pulse with the beat of whatever music you're playing.

Logitech G703 Overview

The Logitech G703 is arguably one of the best wireless mouses on the market, and depending on its current price, could be the right mouse for you. It's subtle design makes it an attractive option for people who want a high performance gaming-tier mouse without the often overdone gaming aesthetic.

It's a pretty desirable option with it's beautiful form factor, modest RGB, and comfortable body grip. As far as features go, the G703 has everything the G403 has, but is compatible with Logitech's PowerPlay wireless charging mouse pad and has the Logitech LIGHTSPEED wireless tech for users who want ultra low-latency that rivals any wired gaming mouse.

G703: Wired + Wireless Connection

The Logitech G703 can be used both wirelessly and with the included braided charging cable. You won't notice any difference in performance or latency in either scenario since Logitech's wireless LIGHTSPEED technology gives you sub-1-milisecond latency which rivals any wired gaming mouse option available. The LIGHTSPEED wireless reciever is low profile and fits into a standard USB slot.

G703: Battery Life

You can expect a solid 18 hours of battery life from a full charge, though many people report 20+ hours per charge. When plugged in, the mouse charges to full in several hours. If you take advantage of the wireless charging with Logitech's PowerPlay wireless charging mat you won't ever have to plug it in to recharge.

G703: Weight

The G703 weighs 117 grams, but has a magnetic 10-gram weight that can be removed to reduce the mouse's weight to 107 grams.

G703: Tracking Resolution

Like the G403, the G703's tracking resolution can be set between 200 and 12,000 dpi, which is easily a broad enough sensitivity range for any potential uses you may have.

G703: Who Should Buy the Logitech G703?

The Logitech G703 is great for anyone who wants a high-performance gaming-tier mouse without an over-the-top gaming aesthetic. This mouse has modest, good-looking, customizable RGB lighting, but would not look out of place in a work setting. If you find yourself switching back and forth between gaming and work, or just want a great looking, high quality mouse that will last you a long time then the G703 won't disappoint.

G403 vs G703: Final Recommendation

If your trying to decide between these two mouses let me make it simple for you. Go with the cheaper option, unless you really want the wireless charging capabilities of the G703. From a daily use standpoint, the G403 and G703 feel like the exact same mouse. Most users, including most gamers, will not be able to tell the difference in latency from the LIGHTSPEED wireless technology, and if you're someone who needs this ultra-low latency, you may want to consider the Logitech G703 Hero or the Logitech G Pro Wireless.

As far as where to buy the G403 or G703, we always recommend Amazon when purchasing electronics because their customer support makes returns and exchanges really simple as well as their low shipping times. That being said, you may want to cross-shopping Best Buy, Jet, and potentially Target for the best price available.
