8R15W-I – Excellent Unit & Service – 5 Stars

This was my second unit from Zero Surge after a great experience with a 2 outlet model(2R15W). This one offers a lot of great features with the same top in class build quality, excellent customer service, and from a family company Made in the USA. Keep up the good work guys.

Seamless protection – 8R15W – 5 Stars

Have had these for a few years now and they work flawlessly. Highly recommend them. Using them mainly for my home audio video. Luckily I haven’t had any surges in my house, but if I do, I know I’m protected. great product would buy again.

Electrical Engineer – 8R15W – 5 Stars

Great product! This is my 3rd Zero Surge device. Purchased a couple of 2R15W in 2021 which have been in continuous service 24/7 since without issue. This 8R15W shares the same outstanding build quality as the 2R15W. Placed my order over the 3-day holiday weekend. It was processed and shipped first business day after and arrived via UPS in 3 days. I like the backside placement of the 6 switched outlets and side placement of the 2 always on outlets, facilitating clean cable management. From my perspective as a retired Electrical Engineer, their design technology is the driving factor for my choosing the Zero Surge product line. The series mode topology is undeniably superior to the MOV shunt approach due to its inherent current limiting nature, particularly with regard to high slew rate transients, and provides the added benefits of EMI/RFI filtering and non-degrading performance. Zero Surge also incorporates an input voltage tracking feature that maintains protection over a wide operating range. The 10 year warranty is testament to the company’s confidence in their products. Excellent sales and product support too. The sales/marketing director appears to be involved in every order throughout the process, with customer satisfaction as a goal. Made in America!

8R15W-I – Great Product and Company – 5 Stars

Needed surge protection in a hurry after a storm took out the sacrificial protection for my expensive audio and home theater system. Ordered Monday at noon and had it delivered and installed by Tuesday afternoon. My system sounds great and I can enjoy it knowing my gear is protected. Great product and super helpful, friendly, responsive team. Can’t speak highly enough about them.

8R15W – Just what I needed – 5 Stars
I purchased an older home with very few grounded outlets and needed to protect my home office. I’m self-employed and live in an area with known power surges, and there’s no way I can take a chance losing thousands of dollars of equipment needed to do my work. I’ve already experienced a power outage and a power surge and this equipment has protected my laptop, extra screens and printer perfectly! Product arrived quickly, and I highly recommend it.

8R15W – Simply the Best – 5 Stars
Excellent product. Rugged, high-quality build, no problems. I needed to reliably protect a large investment in several expensive items (large flat screen TVs, DVDs, several pieces of audio equipment, computers, printers, STBs, among others). The ZeroSurge design concept convinced me initially and now, as I purchased my third ZeroSurge product.

8R15W – Technical Representative – 5 Stars
This is my third ZeroSurge power filter. I am impressed with the build quality of the units, from the sheet metal enclosure to the genuine Hubbell® receptacles. I also like the fact that these do not need periodic replacement like MOV-based consumer-grade surge suppressors.

8R15W-I – Very Affordable High-End Stereo Protection/Improvement – 5 Stars
When I swapped out my old but okay power strip for the 8R15W-I, the sound improvement of my respectable stereo system (Mytek Brooklyn Amp+ & DAC+ w/KEF LS50 Meta speakers) improved immediately and quite noticeably: the soundstage widened, transients and imaging became clearer, reverb became more pronounced and realistic, and low-level information appeared that had been drowned out before (and perhaps connectedly, the background silence became blacker/more quiet), and the overall sound was purer. All of this was gained, along with isolation and protection, at a *very* reasonable price-point. If you look at comparable products on audiophile/stereo equipment websites,, a product from the likes of e.g. Shunyata costs $900 minimum, and that is considered “affordable” in the audiophile world! I think if the mid-high end audio equipment community were made aware of what they could get at only $350, and made in the USA to boot, they would eagerly purchase this product.

Been using this product on my high end audio system and feel safe with the protection it provides. It has weathered many thunder/lightning storms already. Happy to have ZeroSurge protecting my setup. Thanks again.

8R15W-I – Quality – 5 Stars
This product was recommended by an audiophile friend, who has been fortunate to have had the opportunity to been exposed to numerous products over the years. His recommendations have been gold, including this one. I am super happy with the build quality and peace of mind that comes with ZeroSurge’s reputation. I am protecting a McIntosh MA12000. I will be adding additional high end components to my system, also protected by the 8R15W-I, but am only in the home trial process.

8R15W-I – Mr. – 5 Stars
I use this surge protector for my TV & sound system, and another for my stereo system. We have frequent surges at my location, and my equipment is well protected. Thanks.

8R15W-I – Owner – 5 Stars
Thanks again to ZeroSurge on providing my 7th unit! To say I prefer ZeroSurge is an understatement. I’ve used these units on not only my hifi audio system but also all my computers and NAS along with any critical components. No failure of any kind in over a decade of use. Thanks to ZeroSurge!
