A well-designed, well-built piece of hardware, if you can figure out how to use the supporting "HD" software
The example pictured here is in Final Cut Pro. Move the mouse to the right and you begin to scrub later in your Final Cut Pro timeline. Just like a shuttle control, the further in either direction you move the controller the faster you shuttle. Move the mouse back to the center and the shuttling slows. It’s actually one of the more convenient shuttle controls out there right now for one simple reason: the controller is the mouse itself. Since you already have your hand on the mouse, there is no reaching to another control unit to make it work.
But what if you don’t use jog/shuttle controls when editing? I rarely use the jog/shuttle control on my Contour Shuttle Pro (in fact, I’ve changed the jog dial to zoom the timeline) and prefer to use JKL scrubbing instead. I just didn’t use this HD mode on the mouse much. Plus, I found I had to reinstall the driver software a few different times, as the HD mode would just stop working. There is dedicated HD Mouse software that will give you access to some very detailed, custom programming of all the HD Mouse buttons, as well as the gesture-type controls (see below).
In fact, the software is so detailed that I found it rather difficult to set up. You can add any application to the HD Mouse software beyond the few defaults. I tried to add Safari and make the HD vertical mouse movement scroll a Web page, but I couldn’t get it to work the way I wanted. It would be nice if Bella could provide more presets or provide downloadable presets for other, non-editing types of applications. To be fair, however, it does look like you can customize this mouse to do a lot of tasks. I simply found it took more time than I had to give to properly program some of the more advanced gesture-based features.
The other issue I had with the Bella HD Mouse isn’t really an issue with the mouse at all. I normally use an Apple Mighty Mouse and found myself constantly wishing I had the functionality of the tiny scroll ball that is engineered into the Mighty Mouse. After living with the tracking and range of movement that the little rubber scroll ball provides, it’s hard for me to work without it. While the Apple Mighty Mouse feels much more like a plastic toy than the Bella HD Mouse, it’s in the end a not-surprising case of great design and one single great feature trumping overall build quality. While the Bella HD Mouse feels like a much more professional and well-built product, I would rather have the functionality of the Mighty Mouse scroll ball for day-to-day editing and general mousing work.
