Should I buy an air mouse?
For the past 5 years, I have been experiencing severe back spasms due to constant reaching for my mouse. I have bought ergonomic devices but those have not helped.
These air mice look promising. Although I have heard rumors that the mouse pointer on screen does not always align with the device being waived in the air. I hear it always need to be "reset." Is this true? Are air mice worth buying? The logitech one looks good. Does anyone else have any specific recommendations of air mice to buy if they are worth buying? Thank you so much.
