REVIEWS:
1) Solid unit, but check your cables before buying: This is an excellent unit with all connections on the back which helps with cable management. It also has low-volume audio feedback for the hot-keys which is better than my prior KVMs.

However, I was surprised to find it has four male video connectors for the controlled computers. My previous two KVMs had female connectors and worked well with my cables. After spending an extra $15 for 4 video gender changers, everything worked out fine.
