The power strip in general is very nice. Well built, nice design and we really like the USB charging capabilities. HOWEVER, the on/off switch is a joke. If this is going to be used in an environment where you will be turning it on and off a fair amount (every day), I would not buy this again. If the strip is going to be used in a situation where it is left on all the time, then go for ahead and purchase it.
EDIT - HOLSEM saw the above review and contacted me to point out that the "switch" I mentioned was actually a cover for the switch. We checked it out and that was indeed the case; under the cover is a robust switch that should last for many, many years. Satisfied, I ordered several more HOLSEM Surge Protector/Power Strips.
UPDATE (11/06/2018)
So far this product is holding up extremely well. One hundred percent satisfied with zero issues. Those who are hesitant to purchase this product, just go for it, and you wont regret it. If you do regret it, HOLSEM will back you up with their excellent customer service.
UPDATE (9/23/2017)
HOLSEM contacted me personally and have sent me a brand new replacement despite the return window closed.
In terms of customer service, they are EXCELLENT. Never encountered such service before.
I would literally stick with HOLSEM for future purchases, as they are absolutely reliable and are willing to listen.
Regarding the product reliability, I give an update after 2 months of use. For now, i am giving them 5-stars.

I have been using this fine for the past 2-months. This morning, I was working home and I was plugging in my labtop charger into the adapter, and all of a sudden saw a big spark and a "POP" sound.
I immediately removed my charger from the adapter, and instantly noticed a burnt smell and color changed to black.
The adapter still seems to work. I've tried plugging my monitor to it and it seems to be still working. However, I will not use it as i'm afraid it may catch electric fire.
+ The return eligibility has ended 2 weeks ago. I have no way to contact the seller to return or get it replaced.
Really love this power strip. I did a lot of research before I purchased this one. Read all the reviews and decided this one fit my needs. I have different shaped power charging cords and needed them to fit different ways. This works GREAT for just those types. Plenty of room between plugs, able to turn items different ways and still getting them to fit securely and safely. The end has three USB ports which is perfect when you need them without taking up the plugs. Will be back to purchase more of this item soon. Highly recommend. Just had a big thunderstorm in our area with massive amounts of lightning. Our electricity did go out and my surge protector worked just like it was suppose to. Had everything important plugged into it and nothing was done to any of my electronics.
I love this power strip for both its form and function. Works great and looks great. I did have to email HOLSEM in order to register my power strip and to receive the one year warranty extension offered, as their website is not configured securely but that is the only issue I've had. The HOLSEM Surge Protector Power Strip provides more than enough outlets as I'm currently using only half of them plus two of the three USB charger ports. All work as advertised and infinitely more attractive than my old faithful APC Surge Arrest (still going strong since 2001). Additionally, the slots provided on the back of the unit allow for hanging on the wall if so desired.
I will update in future should the basis for this review change. Recommend this product!
There's a reason this surge protector gets high scores and can be found at the top or near the top of every professional review...it does it's job, and it does it well. Unfortunately, there seems to be some people out there who don't understand how electricity works, hence some of the one and two star reviews here on Amazon. Here's a few tips: a microwave rated at 900 watts typically pulls around 1,100 to 1,200 watts from the wall, and surge protectors with multiple outlets like this aren't meant to be used with appliances like microwaves. If you need a surge protector for your microwave, get a single outlet direct plug in that meets UL 1449 safety standards. Also, just because a surge protector is rated at 1,875 watts doesn't mean your wall outlet and/or breaker box can handle the power draw even if you're only using half of that. I guess common sense isn't so common, and it makes me wonder how some people manage to dress themselves much less function on a day to day basis.
Now for the review...
I have over $2,500 worth of electronics plugged into this thing, and I wouldn't be giving it 5 stars if it didn't deserve 5 stars. Here's a list: a custom-built gaming/editing PC including an overclocked Ryzen 2700X and watercooled & overclocked Gigabyte 1080 Ti, 27" 1440p 144hz monitor, 32" 1440p 144hz monitor, Steinberg UR12, uninterruptible power supply, printer, land line phone and whatever Comcast's newest modem is, and everything is working just fine. The Steinberg has the option to be powered by the motherboard or a 5v micro USB plug, so the 5v USB plugs on the Holsem are perfect. The sound of my mic is WAY cleaner now than when I had it plugged into the mobo or when it was plugged into my old surge protector (Belkin F9H710-06). I'm able to turn the gain up higher without as much noise which means less work in post. I'm very happy with the performance of this surge protector and the 20 or so minutes I spent doing research on it paid off. For $33, this thing is a steal.

Purchased this product in at the end December of last year. It was everything I wanted it to be. Less than 2 months later, however, it's making a clicking electricity sound, which is very troubling. Ive disconnected it and stopped using it. I tried to contact Holsem via their website, but the contact us page doesn't work. Their listed phone number there is also 123456789.
So my only resort is this review. I really liked the product and hope it is replaced under warranty, but if you could hear it, you'd be afraid to use it, too.
UPDATE: Epic customer service! Holsem took care of me in 1 day. Thank you!
After reading in the news that a home had about $650,000 damage due to a faulty powerstrip, I decided to replace several old ones that I've been using for over 20 years. The old powerstrips only had sockets for 6 electrical devices so Holsem's 12 sockets was a big advantage. The quality is good but my main concern is that it's UL rated. Looking at the specs for some other powerstrips, I noticed that not all had the UL rating. Some had European ratings which are based on other requirements that I'm not familiar with. I feel safer with the UL rating. Installing a new powerstrip gave me a chance to clean up all the cables behind my computer - a much needed job!
Great outlet, I absolutely love the show space provided. We can plug in many larger box units and charge 3 USB devices while having many smaller plugs in our outlet as well. One of the best designed outlet designs. I also love that the cord from this surger to the wall is pretty lengthy.
I bought this surge protector specifically because of odd sized plugs. I was using another one that had 6 ports. However, I never could use more than 4-5 of them, because odd shaped plugs would take up more than their fair share of room and you couldn't squeeze another one in. I don't know why this is a thing and why there isn't more standardization, but it's a fact.
With this device, I get double the amount of ports and all the odd sized stuff can go on the outside. I've basically only used half of them and have all my devices plugged in that I want to be plugged in. I haven't had a landline phone beside my bed for years, because I didn't have room for a bulky plug when I take almost all my calls on my cell phone. On top of that, I had one port where I was constantly plugging and unplugging something to make room to charge something else.
As an additional benefit, this device has (3) USB charging ports. One of mine on the old surge protector was basically dedicated to a power block that allowed me to charge 2 USB items at once. So these dedicated charging ports will free up, yet another outlet for me.
I do plan to order outlet covers for all the unused ones, to keep dust or debris from getting in them. I was also reading one review that says it might not be the best surge protector out there, but it was the only item I could find, listed as a surge protector, that had the port spacing I was looking for.
I have been buying Holsem surge protectors for the past year.
My first purchase was this very 12 outlet surge protector. I bought it based on overwhelmingly positive Amazon reviews.
From the moment I unboxed it and plugged it in, I was hooked! This is a quality-made surge protector like no other for the price point. It's as if Apple made this product -- that's how perfect it is.
The first thing you will notice is how "loaded" this device is with AC outlets and USB charging ports. As you know already, you can plug up to 12 devices into this unit. The only downside with so many outlets is that they are packed rather close together. This means if you plug in a block type plug, it will take up more than one outlet space. It looks like Holsem has tried to alleviate this problem somewhat by configuring connections on the sides and the middle. If you are lucky, you might be able to get normal and box plugs to coexist together.
In addition to the 12 plug outlets, there are three USB charging connections. Two IQ ports have a charging speed of 5V/3.1A and the third has a charging speed of 5V/1.0A. IC technology automatically detects the device you are plugging into it and then provides the fastest charging.
And what would a surge protector be without overload protection? In the event of such an overload, the safety switch will trip off automatically thus protecting your plugged in devices and ultimately, your home. The adapter is also flame retardant and features a 6-foot cord which gives you plenty of room to place this device exactly where you need it.
As I noted previously, for me it was love at first sight. This is really a surge protector to behold. Once you use this in your home, you won't want to go with any other brand. I have bought two additional slightly smaller 8 outlet surge protectors that Holsem also supports. As of the writing of this review, the smaller strip was remarkably slightly more expensive than this one. So, if that's the case for you it's a no-brainer to go for the larger protector.
On the back of this surge protector are keyholes that you can mount this to a wall or baseboard.
Extremely happy with this brand. As I stated earlier, I won't buy anything else. I believe you'll be just as happy with this purchase.
