I've installed a dozen or so of these so far and have had no failures yet.

Installed in attic, where temperatures are extreme. After 3 months, still working great.

It's an 8-port gigabit switch with all the standards, and does its job on that front. Reasonably sized, fast as far as I can tell, sturdy metal case, nice looking.

This is a solidly built device that will take not just the heat, but vibration and even a certain amount of impact, although I wouldn't beat on it with a stick or anything. It's intended for "industrial" use, so it's going to do the job for anything within reason. Ports automatically adjusted to a variety of devices at different speeds and connected right up without any issues at all, on all ports.

Works well so far. Have one at two tower sites where we need extended operating temperature range. Conveniently these guys also come with redundant power input. I hope they last.

Have had one in use for quite a while now and they do the job they are supposed to. Good quality product easy to install. Nice and compact.
