I would not buy this product again.
The product led lights worked and showed the product was protecting my devices however there was no power to the outlets. The breaker switch also appeared to be working but again no power was detected at the outlets. I had to return the product.

Exactly What I NEEDED!
To power on two Fender Champion 11 25-Watt Amps simultaneously for FX Effects synchronization. Works perfect and protects the Amps too!

I will always buy these products as needed.
Power went out at noonish in Findlay, Illinois. About two hours later power was restored. We found that a circuit breaker had disconnected power to our Router and Modem which were serviced with an Isobar, Tripp-Lite 4 outlet surge protector. We found the suppressor was Fried but the equipment plugged into it was undamaged. With talking to our Rural power supplier they s...

Can't recommend highly enough
I bought one of these 20 years ago and I used it everyday for arcade repair and it was a true work horse. Can't recommend highly enough.

Yes, I would buy this product again.
Great product. Case is all metal and two isolated banks of suppression. I'm currently using it for my computers and sensitive electronics. I still unplug during thunder storms with lightning, but feel protected from all the spikes and trash on the power lines from every day life. Thanks for a great product.

Reliable product with a great guarantee
I have bought two Tripp-Lite Surge Protectors. One is used to protect my digital piano and the other is used to protect my desktop computer and associated equipment. My computer seems sensitive to power fluctuations so I will see if the surge protector helps. I was most impressed with the guarantee that comes with the surge protector, especially for the digital piano wh...

Sturdy and reliable.
This is my 3rd personal use Isobar. This one will be for my new Washing Machine. I've used Isobars for decades. Isobar is considered the standard for the many organizations I have been employed with.

Best specs of the units I have seen
I am using this to protect computers and amateur radio equipment. This surge protector has better specs than other units I have seen e.g. the let through voltage is 330v. Many units that I have had have a let through of 400v or more or they don't even specify it. I think this is important because my laptop charger can only handle about a 300v surge.

Sturdy and robust
Bought after it was recommended by the internet. Its by no means sleek b JJ t makes up for it by its sheer sturdyness. It has a heft and weight to it. Working perfectly so far. Plus points for providing plug inserts for added safety for those who will not be using all the outlets.

This is a very good product. We use them to keep power from surging to our bug lights. I would recommend them to anyone that wants to protect their own products.

Metal body
I was extremely happy to see this was made in the Phillipines. I got this to protect my $3500 refrigerator. I like the metal body.
