i hope they were work in the case of a bad storm

We had a pretty bad storm and had this unit protecting our telephone system.

Soon after installation, we had a bad lightning storm that ran in on my phone line, but thankfully the surge was suppressed by the TrippLite and no equipment was damaged.

We've only had it two days and haven't had a bad storm during that time, I'm keeping my fingers crossed that the reviews were accurate.
