Introduction

For nearly 30 years, Logitech has been building a bridge for people to digital experiences, and

gaming peripherals have always been their strength. They have an unshakable position in this

market. Among these products, the gaming mouse has always been an innovative product that

Logitech is committed to developing. Their new products can always bring novel experiences to

users. One of the most popular product is the G502 series. The engineering design can be

connected to the player’s computer equipment in two ways: wired and wireless. Compared with

its predecessor, the latest generation G502X ( Figure 1 ) has added function buttons that were not

available before.( MrZac2000, 2023) Players can customize the effects of these function buttons

by using Logitech software. For example, you can reduce your workload by customizing these

buttons, this gaming mouse can also use the macro system to achieve some automated

operations. It can automatically complete a series of batch operations and automatically execute

a series of complex tasks and simplify workload of users. These new designs bring an excellent

experience to users.

Background

Logitech was founded in 1981. (Wikipedia, 2023, para. 3)It is a world-renowned provider of

cloud peripherals originating in Switzerland. It started out as an original equipment manufacturer

(OEM) and now operates in more than 140 countries and regions around the world (Wikipedia,

2023, para. 3). The company operates under the Logitech, Logitech G, Jaybird and Ultimate Ears

brands, and operates in the areas of productivity and creativity, esports gaming, video

collaboration, music and smart home. Logitech implements a multi-brand, multi-category

strategy.. The product business is divided into five segments: keyboard, mouse and other PC

peripheral products category, game category, music category, video conference system and smart

home business. Logitech had the first office in Palo Alto, California in 1982. (Wikipedia, 2023,

para. 4 ) In the same year, the first Logitech mouse, the P4, was released. (Wikipedia, 2023, para.

4 ) The Logitech G1, the first G-series mouse, was released in 2005 ( Figure 3 )was released in

2014. (CDRinfo, 2006.) After many years, the first generation G502 ( Figure 2 ) was released in

2014. ( Walton 2014 ) After receiving good responses from the market , Logitech has continued

to upgrade the G502 since then. The latest generation Logitech G502 X ( Figure 4 ) was released

in 2022. (Knapp, 2023)Compared with G502, the newly released G502x continues the classic

asymmetric ergonomic shape of G502. The size is basically the same and the length and

height are similar, but the new model is slightly wider. There are also slight changes in the

surface texture. The weight is greatly reduced and the counterweight is eliminated. (Knapp,

2023)Secondly, the key has been changed, and a dpi adjustment key has been added, which can

be replaced by a cover plate to prevent misclick. (Knapp, 2023) The biggest change is the feel of

the keys; this time the mouse replaced a new mechanical micro. The feel changed greatly and is a

bit similar to the film keyboard on the mechanical keyboard. The new G502X also received

better reviews than the G502. (Tamas_1337, 2023)

List of Parts and Functions

Logitech G502X Gaming Mouse is a mouse for gamers. Compared with ordinary mice, G502x

 has a more novel appearance and more functions. G502x uses light metal as a whole to make the 

overall weight of the mouse lighter than ordinary mice. Secondly, the scroll wheel itself has also 

been changed, becoming a lighter alloy scroll wheel with a rubber cover, and uses an 

asymmetrical grip design, which is more ergonomic. (Rexosorous,2022) Its physical 

specifications: weight 106 grams; height 131.4mm; width 41.1mm,;length 79.2mm  (Logitech)

Players can individually set the lighting color of the 8 RGB LED lamp beads according to their 

preferences. G502X ( Figure 5 ) has three detachable DPI adjustment buttons that allow players 

to change the DPI speed as they like. If you don’t need them, you can completely replace them 

with the included blank covers. There are asymmetrical left and right mouse buttons on both 

sides. G502X has two customizable function buttons on the left side ( Figure 6 ). Players can use
