<h2>The 60-second take</h2>
<p>The <a href="https://www.amazon.com?tag=uzinetwork20-20" rel="sponsored noopener" target="_blank">Logitech MX Master 4</a> is the best productivity mouse you can buy. The magspeed scroll wheel is genuinely faster than any other mouse for long documents. Multi-device pairing is the best in the category. If you work 8+ hours a day at a computer, this mouse pays for itself.</p>

<h2>The scroll wheel is the killer feature</h2>
<p>Most mice have a scroll wheel. The <a href="https://www.amazon.com?tag=uzinetwork20-20" rel="sponsored noopener" target="_blank">MX Master 4's</a> magspeed wheel is something else. It freewheels for hyper-fast scrolling through 500-page PDFs, then clicks back into ratchet mode for precise work. Switching between modes is automatic based on how fast you flick.</p>

<p>I edit 50+ page documents weekly. The MX Master 4 saves me 15–20 minutes a day vs a regular mouse. At $99, the mouse pays for itself in a week.</p>

<h2>Multi-device pairing, perfected</h2>
<p>The MX Master 4 pairs with up to 3 devices via Bluetooth or the Logi Bolt USB receiver. Switching is a single button press. The hand-off is instant — within 200ms.</p>

<p>For anyone with a work laptop + personal laptop + desktop, this is the feature. The Apple Magic Mouse has nothing close. The Razer Pro Click is worse.</p>

<h2>What I didn't like</h2>
<ol>
  <li><strong>Software requires an account.</strong> Logi Options+ now requires a Logitech account to use the customization features. This is unnecessary and annoying. The mouse works without it, but you lose per-app button mapping.</li>
  <li><strong>Right-handed only.</strong> No left-handed version. If you're left-handed, look at the Razer Pro Click or any ambidextrous mouse.</li>
  <li><strong>Size.</strong> This is a big mouse. If you have small hands (under 7 inches), look at the MX Anywhere 3S.</li>
</ol>

<h2>Final verdict</h2>
<p>The <a href="https://www.amazon.com?tag=uzinetwork20-20" rel="sponsored noopener" target="_blank">Logitech MX Master 4</a> is the productivity mouse to beat. The scroll wheel alone justifies the price for anyone who reads or edits long documents. Multi-device pairing is unmatched. Buy it if you work 8+ hours a day at a computer.</p>
