Mice come in all shapes and sizes, but all are not created equal. Some are wireless, some need batteries, some are big, some are small, some need dongles and some do not.

But what if you’re looking to a mouse that can do it all, yet still stay compact? That’s where the Dell Premier Rechargeable Wireless Mouse, MS7421W, can help you out. We were provided one for review, and here’s a look at why it is a comfy mouse for all your devices.



If you’re spending $70 on a mouse as you are with this one, then the design should be quite unique. That’s why you won’t be disappointed here. This mouse looks a lot like a XPS laptop, with a soft woven platinum-colored silver grip on the outside and silver-colored top for the buttons. Even the weight is slim like a XPS would be, coming in at 0.18 pounds, and just 1.4 inches thick.

Cool as that is, it is what is on the inside that matters. Instead of having to remove the bottom of this mouse, to get inside this one, you pull the top off from the sides. Once you do, you get in to find the USB-dongle. Everything is held in place magnetically, and it is a strong hold as the cover never fell off during my regular usage. Having room for a dongle inside the mouse is important, too, as it means you won’t lose it easily.

It should also be noted that this mouse features USB-C on board for recharging. It is nice to see USB-C as this type of port is becoming more common over micro USB. You’ll also find USB-C on rechargeable mice from Logitech, like the Logitech MX Master 3. And, since this is USB-C, you end up 6 months of battery life, with a full charge in just 3 hours.

Dell includes a USB-C to USB-C cable in the box for you, but you’ll need to supply your own charger brick to charge things up. Just note that only charging happens via USB-C. It won’t carry data via the USB-C port, as this is what the dongle is needed for.

Dell says a two-minute charge can get you through a days work. In my time with the mouse, I haven’t experienced any battery issues, and a full charge has lasted me more than two weeks thus far.

Tracking, buttons & connectivity

There’s more to a mouse than just the design, and tracking and connectivity are also important. Here, Dell has you covered. The mouse offers up to 4,000 DPI, and it is adjustable at three other levels: 1,000, 1,600, and 2,400. You can change the DPI from within Dell’s Peripheral Manager App, which installs once you plug the dongle into your PC. The app also lets you program shortcut buttons, check the battery life, and get firmware updates, too.

As far as tracking performance goes, I was able to use the mouse on many surfaces without a mouse mat. It worked on a wooden table, a glass table, a plastic table, and even tracked on the leather of my jeans. That’s all thanks to the optical LED tracker.

But what really makes this mouse cool is it’s ability to connect to different devices at the same time. You can connect and switch across three different devices at once. One connection happens via the 2.4 GHz wireless dongle, and two are reserved for Bluetooth. You can switch between them with a click of a button at the top of the mouse. No need to flip the mouse over, like on a Logitech MX Master 3.

Another thing that’s great about this Dell mouse is the scroll wheel in the middle. Not only does it let you scroll up and down, but the wheel also tilts to the left and the right, allowing you to move left and right in webpages when you have windows open side by side. Paired with the side buttons, this makes navigating the web so easy.

Note that this mouse is certified to work on Windows 7, Windows 8.1, Windows 10, Mac, Linux, Chrome, Android and iOS. Basically, take it anywhere you go.

A nice mouse to buy

If you need a premium mouse, then the Dell Premier Rechargeable Wireless Mouse is one to buy. The comfy design of this mouse is quite unique, and USB-C connectivity makes it easy to charge. Bluetooth and the USB dongle also means that you can use it no matter where you go. You can buy it today from Dell for $70, but it is usually on sale for around $60.
