Buy Gyration GYM2100NA Air Mouse

Basically it is a good mouse for notebook computer and travelling, but not as good as I have expected.

I am a technical training instructor and I do a lot of presentations using PowerPoint. I purchased my first Gyration mouse called GyroMouse Presenter in 2004. I have used it for work on daily basis, on both desktop as well as in-the-air and it is still in perfect working condition today.

The Presenter mouse had a unique egg-shape design, it feels very comfortable holding in my hand when using it for my presentation. The only thing is it is a product with older technologies, it's a mechanical mouse with a roller-ball, there is no scroll wheel, and with low frequency radio signal that is prone to get interfered. Because it's a full size mouse, its weight and a fairly large charging base and AC power adapter made it cumbersome to travel with.

So recently I decided to get a new air mouse. I bought this Gyration Air Mouse GYM2100NA from Amazon. The first impression was good but then quickly I found a problem. It's almost impossible to open the battery compartment without damaging it. It took me more than 20 minutes, with a mini screw driver to prey open the battery compartment.

After almost a moth using this new Air Mouse, here are my thoughts.
Pros:
1) Small and compact, light-weighted travel mouse for notebook computers.
2) It's an optical mouse so no more cleaning the roller ball.
3) Plug-n-play no need for special driver, recognized by Windows as USB mouse.
4) 2.4 GHz radio signal so less prone to interferences.
5) Using two AAA batteries so no need to carry the charging base and AC power adapter.
6) The USB receiver is stored inside the mouse when not used.
7) There is an on/off switch to extend battery life.
8) Oh, and the zippered carrying pouch.

Cons:
1) It's not exactly the best ergonomically designed air mouse. As a guy I have relatively small hands. But even I feel it's awkward to hold the mouse in midair and simultaneously trying to pull the trigger button on the bottom of the mouse. (I miss the egg-shaped Presenter.)
2) The battery compartment is a bad design.
3) Poor documentation for the included GyroTool software. I still have not been able to successfully utilize the 3 assignable buttons.
4) I wish there is a built-in laser pointer. (In this case Microsoft Presenter 8000 seems to have an edge.)

Summary:
Would I recommend this mouse, yes. But I wish Gyration would have continued the original Presenter mouse. Improve it by making it an optical mouse with lighter weight, getting rid of the charging base by using the USB receiver and AAA batteries, and have a built-in laser pointer. Again, I miss that egg-shaped design.
