The Kensington Pro Fit Mid-Size Wireless Mouse is a fairly basic and attractive travel mouse designed to connect to your laptop via a tiny USB wireless receiver. This means you don’t have to unplug your mouse every time you go somewhere; just leave it plugged in and take the mouse with you.

Is this budget-priced wireless mouse a good choice for students and road warriors? We put it to the test to find out.

DSC01510Kensington has a long history of developing affordable and attractive accessories for notebook users. The Pro Fit Mid-Size Wireless Mouse stays in line with that tradition. We’re talking about a simple wireless mouse with a suggested retail price of just $24.99 on the Kensington website (even less at some online retailers).

Build and Design

At first glance the mouse looks a little more like a wireless desktop mouse than a typical travel-sized wireless mouse. That added bulk is the reason Kensington calls it a “Mid-Size” mouse; it’s built specifically for people with larger hands who typically aren’t comfortable with extremely tiny travel mice that practically vanish beneath their hands. That being said, the Pro Fit mouse is quite lightweight (1.6 oz) and has reasonably modern looks with a mixture of glossy and matte black plastics, rubber grips, and rounded edges.

DSC01515Like most wireless mice, the Pro Fit is shaped to provide a comfortable, ergonomic grip for right-handed users. Those of you who are left-handed can still use this mouse but it won’t feel nearly as comfortable in your primary hand. On the bottom of the mouse is the on-off switch, a “connect” button for resetting the device, and a battery compartment for the two AAA batteries (included).

The USB 2.0 Nano receiver is the main reason you can get away with using the Pro Fit as a travel mouse. The Nano receiver is small enough to leave inside your notebook’s USB port at all times. If you do want to remove the Nano receiver when you aren’t using the mouse, there’s a nice little slot on the bottom of the mouse where the receiver fits and is held in place with a magnet.

DSC01519In Use

As mentioned previously, the Kensington Pro Fit Mid-Size Wireless Mouse is designed for people who aren’t comfortable using extremely small wireless mice. However, we ran into an unusual problem while testing the Pro Fit: The main left and right mouse buttons are too easy to press. It might like a good thing to have mouse buttons that are easy to press, but we accidentally pressed either the left or right mouse buttons on a fairly regular basis during our time with the mouse. This can be resolved by not resting fingers on the buttons, but this is a somewhat annoying problem.

Our office tests suggest this mouse stays connected to the Nano receiver up to about 30 ft away, but it was only able to maintain an accurate and stable connection out to about 20-25 feet away from a notebook. The optical sensor is quite precise, and the one-click adjustable setting between 1000 and 1750 dpi should be enough for most users (with the possible exception of some hardcore gamers).

The glide pads on the base of the mouse are perfectly fine for average use, but the tiny front pads were easily gummed up with crumbs or bits of dirt while traveling … making it more difficult for the mouse to glide a desk.

DSC01518Kensington claims that the two AAA batteries will last “up to 12 months” but there was no way that we could confirm that battery life claim because we have no details on how Kensington tests battery life and we can’t spend 12 months testing a mouse. It’s safe to assume the batteries will die sooner if you spend 12 hours on your computer every day and they’ll last longer if you rarely use your PC and flip the switch on the bottom of the mouse to the “off” position. That being said, the included batteries continued to power the Pro Fit during the weeks we spent testing it.


The Pro Fit Mid-Size Wireless Mouse is an affordable travel mouse for anyone who wants a comfortable mouse with a tiny USB receiver that you don’t have to constantly remove from your laptop when traveling. Our only major complaint is that there isn’t enough resistance under the main left and right mouse buttons so sometimes just the weight of your fingers is enough to accidentally trigger a click. Right-handed users will find the Pro Fit extremely comfortable in hand, but this mouse won’t be nearly as comfortable to left-handed users.

Overall, this Kensington travel mouse feels comfortable for users with mid-to-large sized hands without taking up too much space in a bag. On the other hand, people with larger hands usually have fingers with a little more weight and those are exactly the people who will accidentally click the overly sensitive mouse buttons when they don’t want to.

The bottom line is that the low price, diminutive Nano receiver, and ergonomic deign (for right-handers) still make the Kensington Pro Fit Mid-Size Wireless Mouse attractive to many.


  • Low price
  • Good wireless connection
  • Long-lasting battery life
  • Nano receiver is extremely convenient


  • Buttons are too easy to press
  • Only for right-handed users
