Adder CCS-PRO4 (4 Computers / DVI+DisplayPort / Secure KVM Switch / $817.20, was $908.00) Review
The Adder CCS-PRO4 is a 4-computer Free-Flow keyboard and mouse switch with shared USB and audio (it does not switch video), now $817.20, down from $908.00.
It's Adder's mid-tier cursor-control switch line, positioned between the budget AV4PRO-DVI and the certified Cybex-class options, and the current markdown from $908 makes it one of the more competitively priced 4-port switches in this catalog.
A Markdown Worth Noticing
At $817.20 versus its earlier $908.00 list price, the CCS-PRO4 now undercuts the Vertiv SwitchView 300 Series by over $900, though the two do different jobs.
Video-Agnostic by Design
The CCS-PRO4 does not route video; each computer keeps its own monitors, so DVI, DisplayPort and HDMI workstations can be mixed freely while the keyboard, mouse, USB and audio follow the cursor from screen to screen.
Comparison to Alternatives
Versus the Vertiv SwitchView 300 Series (SV340DPH-400) - a 4-port switch that also routes video, at roughly double the price. Versus the Adder ADDERView PRO (AV4PRO-DVI) - a cheaper DVI video KVM for a single shared monitor. Versus the Adder CCS-PRO8 - the 8-port sibling in the same line, worth it for larger desks.
