First Impressions:

When I first opened up the package for the Kensington Si750m, I couldn’t believe how small it was.  Having viewed the pictures of the mouse online, I thought it would actually be a bit larger.  At first, I was not sure if it would work for me since my hands are very large.  However, after I had used the Kensington Si750m for a while I was able to adjust and find a best way to hold the mouse.

Using a small notebook mouse with a large hand takes some adjustment and getting used to, the benefit is being able to use the mouse in tight places and it’s easy to stow when moving about (view large image)

In addition to the nice compact size, the mouse is also very responsive.  With the cheap mouse that I previously used, I would need to use large hand gestures to move the pointer across the screen.  However, with the Kensington Si750m, I am able to move the mouse two inches and cover the entire screen.  At first, I had a hard time adjusting to this, but now I LOVE it!  I don’t think I could ever go back to a cheap mouse.

General Usage:

I have been using the Kensington Si750m for three weeks now.  One thing that has been convenient is the long range of the wireless.  I tested it and discovered that it has a range of around 30 ft.  This could be very helpful if you were giving a presentation and could not have the laptop very close to you.

The wireless dongle conveniently fits into the Si750m.  To access the slot where the dongle and the battery are located, you need to push two buttons in that are on both sides of the mouse.  These two push buttons are built right into the rubber grip on the side of the mouse.  They are very hard to detect, but you can feel a slight indentation in the grip.

Left side of the mouse, notice the one push to open button is slightly visible at the back of the rubber grip (view large image)

The Kensington Si750m is also very durable in my opinion.  As an example, it survived being thrown through the air while being in my backpack and hitting the dashboard of my car.

The right and left click buttons feel very good and the scroll wheel works smoothly.  The wheel makes a slight clicking sound as you scroll.  The Si750m is very responsive to every click.

Here is a picture of both buttons and the scroll wheel (view large image)

Another neat feature is that the laser is actually invisible.  It is very nice if you want to use the Si750m in a dark room but you don’t want to bug people.

In conclusion I believe the Kensington Si750m is a great USB wireless mouse that deserves to be on any laptop owners Christmas list who is looking for a new notebook mouse. The mouse is comfortable and the wireless range is amazing.
