Kensington SlimBlade Trackball Mouse (K72327U)

Kensington SlimBlade Trackball Mouse

The trackball mouse of choice for professionals looking for a sleek productivity tool in their home office. The Kensington SlimBlade Trackball  is unique because of its twist scrolling. Simply spin the trackball sideways and you cruise up and down documents and web pages. The low profile design offers comfortable ergonomic support and dual lasers create precise cursor control to minimize hand and wrist movement.

I purchased this trackball for my office use. Prior to this, I tried to extend the life of my Microsoft Trackball Explorer 1.0 for as long as I could… but that could only last so long. Eventually I had to make the hard choice to find a new trackball. It is a niche market, so there’s not a lot of choices, especially if we are talking about a trackball that does not rely on your thumb as a primary movement mechanism.


Kensington truly has outdone themselves on this one. The Kensington SlimBlade Trackball Mouse is slick, with a large red ball and four programmable buttons. However, what makes this mouse very unique is it’s scrolling mechanism. There are other trackball mice that have rings around the ball to serve as scrollers… there are even some trackballs (like the original Microsoft Trackball Explorer 1.0) or the new  ELECOM that utilize the side scroller wheel for the thumb (one of my favorite options). The blade uses the ball itself as a scroller! Scrolling is as easy as simply turning the ball.

The Kensington SlimBlade Trackball mouse comes equipped with a rubber tab on on side and a slot on the other. This can be used to link multiple Kensington SlimBlade Trackball mouse together if needed.

After using it for a few years, it is easily one of the best trackball mouse ever made.

Small Downside

The one and only downside to this device: Every so often, you will notice the motion of the cursor become choppy or not move in the desired direction. This is because of dirt and oil collecting on the reader points under the ball. Thankfully, resolving this problem is as simple as pulling out the ball and using a q-tip to clean the obvious dirt collections.


Wish a wireless option was available with a usb-c charger.


In conclusion here, this is easily my top 2-3 mouse. I believe if Kensington ever put out an update to this device with some of the more modern options, it would indeed be the best.
