Buying guide: Computer Peripherals
Featuring a steep 62-degree vertical angle and five adjustable DPI levels from 200 to 1600, the ProtoArc EM05 NL is a highly comfortable ergonomic trackball mouse for budget-conscious office users. While it excels at reducing wrist strain and saving desk space, the awkward scroll wheel placement may frustrate users with smaller hands.
Ideal for office workers seeking wrist pain relief in tight desk spaces, but should be avoided by users who rely heavily on quick, effortless scroll wheel clicks.
