In the usual Amazon manner the product was delivered super fast. So unpack - install - works! I use the KVM-0221 with a Desktop PC with Windows XP and a laptop with Windows 7. The change is quick and easy (2x Scroll). The delay is hardly worth talking about, and also the presentation on my widescreen TFT is the same as without a switch. Nevertheless, there is a little thing to complain: When changing to the XP computer sometimes there is a delay of about two seconds until the mouse and keyboard to address again. All in all, the device works as described, it is compact and its price definitely worth it. So here: strong buy recommendation.
