Query: Poor Choice for a critical app

We purchase a dozen of these switches a year or so ago. All but 2 have failed. They heat up over time and then the network speed drops to nearly nothing. The user still sees the network but bandwidth is almost non-existant. If you need a cheap switch for a network go with a Linksys or if you need to step down a bit a D-Link.
