I've had a lot of KVMs. It's not the best and most feature-rich app, but it works as advertised. The unit has been running for several months now and is so responsive that I don't believe it's a $30 KVM. It would be nice to have keyboard shortcuts for switching machines, but the fact that this doesn't require an external power supply more than compensates for the "inconvenience" of pressing a button on the device. This was a great purchase, I recommend it to anyone who needs to simplify their desktop but isn't going to switch machines every few minutes.
