Logitech ERGO M575S Trackball Mouse Just $39.99 — Back at Its Black Friday Low!

If you've been waiting for the right moment to upgrade your desk setup with a proper ergonomic mouse, today is that day. The Logitech ERGO M575S Wireless Trackball Mouse has just dropped to $39.99 at Amazon — a full 20% off its regular $50 price tag, and matching the lowest price we've seen on this mouse since Black Friday. All four color options are included in this deal, so you're not stuck choosing from leftovers.

This isn't some random no-name peripheral. The M575S is Logitech's updated version of one of the most beloved ergonomic mice on the market, and it routinely lands on "best ergonomic mouse" lists across tech publications. If wrist pain, carpal tunnel concerns, or plain-old desk clutter have been on your radar, a trackball mouse can genuinely change your daily computing experience — and at $39.99, the Logitech M575S is the best value entry point for doing it right.

Why a Trackball Mouse? (And Why This One?)

Look — most people have been using the same basic mouse design for decades. You push a hunk of plastic across a desk pad, your wrist rotates, and after eight hours of that your forearm starts screaming at you. Sound familiar? That's because traditional mice require constant arm and wrist movement to navigate the screen. A trackball mouse flips this completely: the mouse body stays perfectly still on your desk, and you control the cursor by rolling a ball with your thumb. Zero hand movement. Zero wrist strain. Just smooth, precise cursor control.

Once you make the switch, it's hard to go back. Trackball mice are especially popular among:

• Remote workers and office professionals who spend 6–10+ hours daily at a computer
• Graphic designers and creative professionals who need fine cursor precision
• Gamers who want alternative control in strategy and simulation games
• Anyone dealing with wrist, forearm, or shoulder fatigue from traditional mice
• Folks with small or cluttered desks — trackballs don't need movement space

And when it comes to picking a trackball mouse, Logitech's ERGO M575 line has been the go-to recommendation for years. The M575S is the 2024/2025 updated model — improved connectivity, better build quality, same legendary comfort.

What You Actually Get: Logitech ERGO M575S Specs & Features

Let's break down exactly what makes this mouse worth your $39.99:

🎯 Ergonomic Design Built for Long Sessions

The M575S is sculpted to the natural contour of a relaxed hand. The moment you place your palm on it, you'll notice how it supports your hand instead of forcing it into an awkward position. The body keeps your wrist in a more neutral posture compared to standard mice, which reduces the micro-tensions that build up into repetitive strain injuries over time. This isn't just marketing fluff — it's why occupational therapists and ergonomics specialists have recommended trackball mice for decades.

🖱️ Thumb-Controlled Trackball for Precise Cursor Movement

The large trackball sits comfortably under your thumb, giving you smooth and accurate cursor control without moving your hand a single millimeter. Whether you're navigating spreadsheets with pixel-precise accuracy, doing creative work in Photoshop, or just scrolling through your browser tabs, the thumb trackball delivers surprisingly fine control once you spend a few days adjusting to it. Most people fully adapt within one to two weeks and never look back.

🔋 18-Month Battery Life (Yes, Really)

This is one of the M575S's most impressive specs: up to 18 months of battery life on a single AA battery (included). Think about that — you might charge your phone daily, but this mouse could last you a year and a half without touching a battery. The battery-sipping efficiency comes from Logitech's power management system that automatically goes into sleep mode when inactive. For anyone who hates the hassle of charging peripherals or swapping batteries constantly, this is a massive win.

📡 Dual Connectivity: Bluetooth + Logi Bolt USB Receiver

The M575S gives you two connection options:

• Logi Bolt USB receiver — a tiny, secure 2.4GHz dongle that plugs into any USB-A port for an instant, low-latency wireless connection. Great for desktops and USB-rich laptops.
• Bluetooth — connects to any Bluetooth-enabled device without using a USB port. Perfect for MacBooks, tablets, or ultrabooks with limited ports.

Both connections are encrypted and stable. You can even switch between devices quickly if you're running a dual-computer setup.

⚙️ 3 Programmable Buttons

Beyond the standard left click, right click, and scroll wheel, the M575S includes three programmable buttons you can customize using Logitech's free Options+ software. Assign them to whatever workflows matter to you: copy/paste shortcuts, media controls, screenshot triggers, browser back/forward, application switching — the list is only limited by what you need. It's the kind of customization that genuinely speeds up your workflow once you set it up.

🖥️ Works on PC and Mac

Full cross-platform compatibility. Windows, macOS, Chrome OS — the M575S works seamlessly across all of them. The Logitech Options+ software is available for both PC and Mac for deeper customization, but the mouse works perfectly out of the box on any system without installing anything.

How Does the M575S Compare to the Original M575?

The M575S upgrades to Logi Bolt which provides better signal security (important for business/office environments), and adds more color choices. The slight reduction in battery life is a real-world non-issue for most users — 18 months is still extraordinary for any wireless peripheral.

Is This the Best Price We've Seen?

Yes — and that's a fact worth emphasizing. The Logitech ERGO M575S regularly sits at $49.99. It dipped to $39.99 on Black Friday 2025, came back up, and has now returned to that same low. Price trackers show this is tied for the all-time lowest price on record for this mouse. If you've had it on your wishlist, there is genuinely no reason to wait any longer.

These sale prices don't always last long. Logitech and Amazon periodically run these discounts, but when stock sells through at the sale price, it can jump back up within hours. The Slickdeals community flagged this deal earlier today and it's already generating significant buzz — which means buying now is smarter than waiting to see if it goes lower (it won't).

Who Should Buy the Logitech ERGO M575S Right Now?

Let me be direct: if any of these apply to you, buy it.

• ✅ You work at a computer for more than 4 hours a day
• ✅ You experience wrist fatigue, forearm tension, or shoulder strain from mousing
• ✅ Your desk space is limited and you hate the idea of a large mouse pad
• ✅ You've been curious about trackball mice but didn't want to spend $80–$100 on a premium model to try the concept
• ✅ You travel with a laptop and want a mouse that works without needing a surface
• ✅ You need a reliable, long-lasting wireless mouse without constant charging

At $39.99, the M575S is accessible enough to try without feeling like a big gamble. And the overwhelming verdict from thousands of users is that the adjustment period is worth it — most people who switch report they'd never go back to a traditional mouse.

The Bottom Line

The Logitech ERGO M575S at $39.99 is a legitimately great deal on a legitimately great product. This isn't a brand you're taking a chance on — Logitech has been making the best peripheral hardware in the business for decades, and the M575S is one of their most refined products. The combination of ergonomic design, excellent battery life, dual connectivity, and programmable buttons at this price point is hard to beat in the trackball mouse category.

Whether you're building out a home office, battling wrist fatigue, or just ready to upgrade from your basic $15 mouse, this is the pick. Grab it at $39.99 before prices bounce back up — and do your wrists a favor while you're at it.
