Fantastic engineering

Awesome holder. Follow the directions. This appears to be German manufactured and very well thought out. Great having my rig off my desk - more room for my second monitor!

Pay Attention

Pretty damn good, instructions are on the right in English. Took me a hot minute to find it and was so close to getting back into Duolingo and learning German.

These surge protectors are rated some of the best you can get
These surge protectors are rated some of the best you can get, so I have been purchasing them for many years. Even though their shell is made of plastic, I've had excellent luck with them over the years without any problems. Recently, one of them had the green light stop working intermittently. I emailed APC and got a replacement without a bunch of hassle. I simply sent them the serial number on the current one and they sent a replacement. It's been a long time since I've experienced this kind of customer support from anywhere. I have to say that APC's customer support is excellent and I will continue to buy their products without question.

I have my Google Fiber router plugged into this. I don't think this product worked as advertised, a lightning storm destroyed the router.
