Several mice of both in the headline first-mentioned brands were me in the work under Photoshop too vague, unfeeling and my "medium-sized" hand after extended photo editing sessions too strenuous. When I had the opportunity with another user, try the Anchor Mouse, I was surprised at how I precisely thus filigree work with very loose hand could perform. Given the low price, it was not a great risk to designate the mouse. Today, after about 10 hours photo editing with Photoshop and Lightroom with the new input device, my judgment is very positive. Even after several hours continuous use my hand is much more relaxed than when my predecessor mice. The work is extremely precise - not least because of good sensitivity adjustment that allows an individual adaptation to personal taste.
Very good also: the mouse turns off after several minutes of inactivity ... and after a single click any button once again. This saves battery power.
Surprisingly, however, unequivocally: I have a new Personal Best In Test!
