Perfect

Exactly what it is sold as. Sturdy and durable. Was excited to get this to protect my new AV equipment in my new apartment.

This is the perfect solution

The product is very sturdy and durable. I have no fear plugging in my expensive audio equipment and it is completely silent and creates no interference with my audio.

Built like a tank!

I bought this for my electronics lab and it us working out perfectly! It's built like a tank and has a lot built in features that attract me. I've only had it for a few weeks but it looks and feels like it will probably last me my whole life time. I will definitely be purchasing another one soon.

Maybe

Nice PDU but the internal fuse should be extended to an externally accessible fuse holder so the fuse can be replaced by owner if needed. Also a small, inexpensive voltage meter would be helpful to be able to monitor line voltage.

Never trusting a cheap power strip to suppress surges again.

I bought two of these when a recent power spike took down a couple of my portable USB hard drives, despite being behind a UPS and on a surge suppressing power strip. What I appreciate most about the 8-outlet Isobar is that the outlets aren't crowded together. I don't have any space conflicts between odd shaped "wall warts" that can't be resolved. An added bonus that I didn't expect are the little outlet covers that keep dust out of unused outlets. Indicator lamps tell a clear story at a glance. The generous cord lets me place it out of site and the angled flat outlet resolves any conflicts at the back of my *New* UPS or wall outlet.

Well Built

Well built with a solid metal case and held together with screws. Generous 12 foot cord makes it versatile for any installation. Surge protection is best amongst its competitors. I have many of these units throughout my house.

I own more than 10 of these and am very happy

After seeing a video about a ham radio operator who lost 2 generations of equipment from a plastic power strip that started a fire, I replaced all with metal ISOBAR8ULTRAs.

Yes I would buy it again.

I used it to protect my stereo system. I can only say, it's well built and seems like a great value compared to others I've looked at. As far as satisfied , I will only be able to tell if there is a power serge.

Robust construction, built for the long haul.

This unit was bought for my audio system as an upgrade to the cheap surge suppressors sold at local stores. It did not disappoint. It's more robust than anything I've had before and should do the job of protecting my expensive electronics. It's worth the money.

Protection Well Worth It

Used Isobar products back in the day when I was a IT network admin in NYC. Now I live in heavily wooded area between steep hills lined with trees. The trees come down on the over head power lines and my computer gear is subject to full outages, bouncing yo-yo power, and major spikes. Got the Isobar 8 to protect against the dangerous zaps. Like the sturdy build, indicator lights and it's roomy enough to fit all my plugs. It's a great value and well worth it to avoid the nightmare of replacing a fried router & other mission critical gear. It gives me great peace of mind.

Must have for any sensitive electronics.

Cream of the crop when it comes to surge protection. Features such as isolated filter banks allow for a reduction in electrical noise accross the outlets, ideal for anyone running audio equipment especially.

Peace of mind

I live in a basement apartment and want to have some houseplants to give the living room some life. I bought some powerful LED lights to give some light to my succulents and I was worried I would over load a regular surge protector. With this Isobar, I have peace of mind to leave the lights on while I am at work. Thank you for a great product.

Learn from me and buy a Tripp-Lite.

A tank for plugs. I love this thing, the build quality is crazy. I bought this after a cheap Amazon surge protector didn't save my gaming PC from an outage. That was very expensive. First thing I did was a lot of research and buy these Tripp-Lites for our expensive electronics. Outstanding build quality and much higher joule rating has given me good peace of mind, and has me wanting to get one of their whole home ones that you plug into the circuit panel.

Swear by Tripp Lite for performance & value

I use this for home theater coverage of the tv, disc players, cable box, HD antenna & game console. A LCR 2400 covers the pre-pro & amplifiers. You can't go wrong with Tripp Lite.

I would never buy this product again!

For 10 years we used a excellent HT10DBS for our audio/visual rack. The reset switch started to flicker so we purchased this Isobar unit. Whe we plugged it in all lites showed normal. Plugged in our componets from the rack and nothing worked. Tested the duplex outlet and the tester showed correct wiring. Test this unit outlets. 1 showed reversed hot and nutural and another showed hot - ground reversed. We currently use 2 other Trip-Lite units and anther brand battery back up unit for our computers, monitors, mosumes, and printers. I can't tell you how disappointed we are and yes we sent it bck to amazon.

Pleasantly surprised

By Felipe

based on the amazon reviews, my main concern for the purchase was spacing b/w plugs since both rows of plugs have the ground part orientated at the same direction. at least for my use case, this was not an issue, maybe for bigger plugs than what i have? so far my only complaints are 1) i wish this 8 outlet came with a shorter cord similar to the 6 outlet version(at the time of purchase the 8 outlet was a couple of dollars more expensive than the 6). 2) I wish they included a mounting/drilli...

Tripp-Lite ISOBAR is the best; well worth the price.

By John

I own 5 Tripp-Lite Isobar surge protectors in 4, 6, and 8 outlet sizes. They are the best. The surge protection has higher capacity (more Joules) than most. The diagnostic LEDs include detection of proper grounding as well as polarity check and protection status. The heavy duty on/off switch is illuminated and includes an overload/short circuit breaker. MOST OF ALL, the case is metal, and the outlets are independently mounted sockets, which means that risk of fire due to faulty appliances or ...

Let the Tripp Lite Isobar Surge Suppressor be your first line of defense against power surges, spikes, and line noise. This premium surge suppressor is equipped with an impressive array of high-quality components, housed in a nearly indestructible all-metal case. Its unique noise filtration system sets the Isobar apart, providing the highest level of protection available in a multi-outlet strip.

The robust surge suppression circuits with sine-wave tracking offer unparalleled protection against even the most severe surge conditions. These circuits exceed IEEE 587 category A & B specifications, reducing 6,000V test surges to harmless levels under 35 volts.

The Isobar's distinctive protection system combines large toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors, and multiple layers of metal oxide varistors. These components form exclusive isolated filter banks that effectively remove EMI/RFI interference, including noise generated by other connected devices.

The ISOBAR6ULTRA model offers eight outlets, strategically arranged in three filter banks. This design helps prevent system crashes, reboots, and performance issues common when noisy system peripherals are powered off and on. With a surge suppression rating of 2350 joules/97,000 amps, this device offers network-grade protection.

The widely spaced NEMA 5-15 outlets can accommodate up to four large transformer plugs without blocking other outlets. Diagnostic LEDs provide immediate confirmation of power availability, line fault, and protection status. Trust the Tripp Lite Isobar Surge Suppressor to provide superior protection for your valuable electronics.
