Overview of the Logitech M720 Triathlon Multi-Device Wireless Mouse

The Logitech M720 Triathlon Multi-Device Wireless Mouse is priced at $44.99, making it about 55% cheaper than the Logitech MX Ergo S, which retails for $99.99. This mouse is designed for versatility and endurance, featuring a battery life of up to 24 months on a single AA battery. It supports multiple operating systems, including Windows, macOS, Chrome OS, Linux, and iPadOS. With its ergonomic design and hyper-fast scrolling capabilities, the M720 is a suitable choice for users who switch frequently between devices and who want a reliable, long-lasting mouse.

The M720's dual connectivity options allow users to connect via Bluetooth or a USB Unifying receiver, which can handle up to six Logitech devices simultaneously. This feature is ideal for multitaskers. Its customized button settings can enhance productivity, making it a solid choice for office workers and tech enthusiasts alike.

Overview of the Logitech MX Ergo S Advanced Wireless Trackball Mouse

The Logitech MX Ergo S Advanced Wireless Trackball Mouse comes with a significantly higher price tag of $99.99. It is designed specifically for ergonomic comfort, featuring a unique 20-degree tilt angle that reduces forearm muscle strain by 27%. This mouse is particularly beneficial for users who may experience discomfort during long periods of use and prefer a stationary design.

The MX Ergo S also boasts advanced thumb control, allowing for precision tracking with minimal hand movement. This mouse connects via Bluetooth or the included Logi Bolt USB receiver, supporting easy switching between devices. Its rechargeable battery offers impressive longevity, providing up to 120 days of use on a full charge, or 24 hours from just a one-minute charge, making it convenient for users who are always on the go.

Design and Ergonomics

When it comes to design and ergonomics, the M720 is crafted for a comfortable grip with a sculpted shape that fits well in the palm of the hand. However, the MX Ergo S takes ergonomics a step further with its 20-degree tilt, which is certified by ergonomists to improve comfort and reduce muscle strain. This difference in design philosophy makes the MX Ergo S particularly appealing to users who prioritize long-term comfort over mobility.

While both mice feature a rubber body, the MX Ergo S's design is specifically tailored for medium to large hands, which may not be ideal for users with smaller hands. The M720, on the other hand, is designed to accommodate a broader range of hand sizes. This makes the M720 more versatile in terms of user compatibility, but the MX Ergo S excels in comfort for those who find traditional mice uncomfortable.

Features and Customization

Both the M720 and MX Ergo S offer customizable buttons, but the MX Ergo S provides a more advanced configuration through its Logi Options+ App. Users can assign shortcuts and Smart Actions to the six programmable buttons, which can significantly improve productivity. The M720 also allows for button customization, but it may not offer the same level of sophistication as the MX Ergo S.

The M720 features hyper-fast scrolling that is particularly useful for navigating lengthy documents, while the MX Ergo S offers a unique thumb control system that gives users the ability to switch between speed and high-precision tracking easily. This feature can be especially beneficial for graphic designers or anyone who needs precise cursor control.

Connectivity Options

Connectivity is a strong point for both products. The M720 supports Bluetooth and a USB Unifying receiver, allowing connection to up to six devices simultaneously, which is ideal for users who work across multiple systems. This flexibility makes the M720 a great choice for users who frequently transition between devices.

The MX Ergo S also offers dual connectivity options, including Bluetooth and the Logi Bolt USB receiver. However, it is particularly designed for users who switch devices often, thanks to its Easy-Switch button. This feature allows for seamless transitions between two connected devices, making it convenient for users who may be using a laptop and a desktop simultaneously.

Battery Life

Battery life is another area where the M720 excels with its impressive 24-month life on a single AA battery. This feature is particularly appealing for users who want a low-maintenance option that doesn’t require frequent charging.

In contrast, the MX Ergo S, while rechargeable and offering up to 120 days of use on a full charge, requires occasional charging. However, it also provides a quick-charge option that gives users up to 24 hours of use from just a one-minute charge. This could be a deciding factor for users who value quick charging over long battery life.

Price Comparison

Price is a significant differentiator between the two products. The Logitech M720 is priced at $44.99, making it a more budget-friendly option compared to the $99.99 price of the MX Ergo S. This price difference of about 55% can be a crucial factor for users who are looking for quality without breaking the bank.

While the MX Ergo S justifies its higher price with advanced ergonomic features and a sophisticated design, the M720 still offers substantial value for users who need a reliable mouse for everyday tasks and prefer a more economical option.

Which should you buy?

Choosing between the Logitech M720 Triathlon Multi-Device Wireless Mouse and the Logitech MX Ergo S Advanced Wireless Trackball Mouse ultimately depends on your specific needs. If you prioritize comfort, ergonomic design, and low muscle strain during extended use, the MX Ergo S is worth the investment at $99.99. However, if you are looking for a versatile, budget-friendly mouse that delivers excellent performance and battery life, the M720 at $44.99 is an outstanding choice. Consider how often you switch devices, your hand size, and whether you value high-end ergonomic features when making your decision.
