This isn't a small office/home office switch as the first reviewer stated, it's a hardened industrial switch made to withstand dirt, grime, and temperature fluctuations. It's more suited to connecting robotic welders in a machine shop than to any small...
A really tough switch that withstands anything you can throw at it. Really, you don't get tougher than this for factory use. It even feels substantial when you pick it up. Has an extended temperature range, so it's fine with conditions in a hot shop. Also
A bit short on MAC addresses, probably because it's designed to link industrial machinery, not PCs. DIN rail bracket for this switch is rather expensive
