False

It might be the right choice if the shape is ergonomically
correct for your uses, but Logitech's "Invisible light"
opticals use less power, tend to run for closer to a year.

I don't know "all" of the Logitech models that use this
technology but at least the V200 Notebook, LX5, LX7,
MediaPlay, and probably one or two more though availability
in any particular geographic region may vary.
