Built Like a Tank… Maybe Too Big
This thing is solid. The build quality is exactly what you want when you’re hanging a PC under a desk—sturdy steel, secure mounting, and plenty of adjustability to fit larger cases. It definitely does its job of getting your tower off the floor and out of the way.
That said, size matters here—and this is built for big cases. If your setup is more compact, it is overkill. Definitely measure before you commit, because while the adjustability is nice, it’s clearly designed with larger towers in mind.
Pros:
Very sturdy, confidence-inspiring build
Adjustable to fit a wide range of larger PC cases
Keeps PC off the floor (less dust, more space)
Can mount under desk or on wall
Cons:
Oversized for smaller or mid-sized builds
Requires careful measuring before install
Bulkier than some alternative mounts
Bottom Line:
A heavy-duty mount that does exactly what it promises—just make sure your PC actually needs something this big before you commit.

My god
Build Quality
The steel construction is very solid and feels durable enough to support a desktop tower or similar device. The powder-coated finish also helps protect against scratches.
Comfort / Ergonomics
Mounting a PC under the desk helps free up floor space and improves overall desk organization. It also keeps the computer elevated away from dust and improves airflow.
Features
The adjustable frame allows it to fit a variety of PC sizes, which makes it versatile. The mounting brackets feel strong and secure once installed.
Ease of Use / Installation
Installation requires basic tools but is fairly simple. Once mounted, the adjustable brackets make it easy to secure the computer in place.
Cleaning / Maintenance
Keeping the PC off the floor makes cleaning around your desk easier and helps reduce dust buildup in the computer itself.
Overall Impression
This mount is a great solution for anyone wanting a cleaner desk setup. It’s sturdy, adjustable, and keeps your computer safely mounted under the desk. Excellent for improving workspace organization.

Rock Solid and Computer / Wall Safe! Last PC Mount you'll ever need.
This is the hardware that you want in your office: robust, no-nonsense, and able to boss you around its workload. I installed a full size PC case/server in it, and it is rock solid once you lock it in. The open-frame design also merits a mention here as it greatly improves airflow and allows you to access ports on the motherboards and other hardware on your rig should you want to during your gaming sessions without bringing too much heat inside and causing headaches. The width of the holder can be adjusted (approximately 7.7” through 11.8”) in width and (approximately 20” through 25.8”) in height so it fits a large variety of towers, so you don't have to worry whether it could fit your set-up or not. Smaller towers may have substantially more wiggle room though.
The mount's weight limit is no joke—up to 44 lbs—so you're not sacrificing stability just to save a few bucks. The shells are quite secure, although some people may have wished for a little more tightening bite; they still prevent your equipment from falling off if you accidentally bump on a wall, which is more important than you may think.
A little nitpick: the lower wall-mount bracket could have a couple of extra pilot holes to reduce twisting over time. Not a breaker, just a heads-up for all of you who are looking to the long term. Altogether, it's a reliable, solid fix that is well worth the cost, particularly if you're cramming space and airflow in a tight configuration.

Best for a large PC case, works on smaller towers with mods
This thing is solid! I strongly recommend setting your tower on it to get a feel for the orientation you want before attaching it to your desk or wall. I had to re-mount mine because I had it positioned too far back to be able to plug cables into the PC tower. When the ad says its for a large PC tower they are not joking. I would consider my PC case to be a fairly average size but the bottom clamp and side arms don't hold my case at all. Theres a z shaped bracket included to attach to the main support and let it contact the desk or wall surface behind it. I used this part to wedge between the bottom clamp snd my PC case to hold it in place. My mount is still very sturdy without that bracket in place. I cheated during install and stacked some books under it to bring it up to the height of the bottom of my desk, made easy work of it. I really want to give it 5 stars but unfortunately the fitment issue leaves me hanging, literally. Maybe I will update my rig and get a larger PC case down the road. What I love about this item is my tower used to be on my desktop. Now its tucked away neatly and I was able to separate my 2 monitors more. Feels like a whole new workspace with less clutter and more table space for projects. Good item.

Attractive design+color, slender profile, excellent functionality, budget price (8 outlet model)
Color: Black, Size: 8 Outlet, Style: Outlets Only, Color: Black, Size: 8 Outlet, Style: Outlets Only
This is exactly what I wanted. (It’s even better - slimmer, easier to handle cord, than the Belkin in this design style.) Perfect fit for the lower shelf of my night table. To charge my phone, iPad, Bluetooth headset, and the like (plug my lamp into it as well, for convenience-sake not surge protection). The 8 outlets are perfectly spaced/placed.
I briefly considered the model with the USB cord plugs directly into the unit, but for me, at this point, for this purpose the extra price didn’t seem worth-it. My USB charging adapters aren’t that bulky, and with this design they can be plugged side-by-side.
I do like the convenience of that design, with the USB plugs, and will likely get it in the future, and move this one to either my home-office, or dressing area. So, this “basic” one wouldn’t be wasted. And meanwhile it’s a great budget option that sacrifices none of the design, style, or function. It’s attractive, useful, well conceived/designed and executed. For well under $20. Nice color too.
Would be perfect anyplace. Though I’d think this more basic model isn’t intended for multiple multimedia devises all in one - looked like they had more suitable models for if you wanted to say plug in your TV, your game console, your streaming and/or cable - do they still call it that? - box/devise, your speakers with or without subwoofer, along with your modem and WiFi-router all into one. Someone, who works with high end electronics and/or an electrician/engineer correct me if I’m wrong. But I’d get a model - of this same device if there’s one of suitable capacity - which that’s meant to handle such a load for my entertainment center. I think another reviewer talked about joules and capacity, I think it was for this model. Or at least this manufacturer.
Though I don’t see it being convenient for travel - not sure about that question there, maybe more convenient than some other styles; certainly not anywhere that’s not 120V, and I doubt that at this level it’s sufficient protection for anywhere with radically irregular electrical/voltage supply, not just the occasional spike, like say - Malawi Africa for a random example out of personal experience, for something like that you’d actually have to spend money and get a proper UPC, not to mention bulky-bulky, but that’s not relevant here, for this, just this isn’t something like that. This is for use with stable electrical and voltage supply, should give perfectly adequate protection for the occasional spikes and surges such as those following a power outage, within the design specification.
