I purchased this hub to upgrade a DIY NAS that I'd previously built using a Raspberry Pi and four Seagate removable hard drives. The system kept failing one or more drives on the previous hubs I'd used, which I presume weren't delivering sufficient power. This one has the system running flawlessly.
Data transfer is also great; I've built this system as a RAID-10 array, and data transfer is faster now, through this hub connected to a single USB port on my Raspberry Pi, than it was previously through two cheaper hubs through 2 ports. Highly recommend.

The product is of good quality, works great...the only bad thing is that the green led's don't turn on, only the one red led turns on...almost returned, but decided not to go through that process, due to, it will be installed in the back of my drawer chest...out of view...

This works well enough just as a USB hub. I had hoped with the power cord it would provide enough juice to charge my phone, but alas, plugging in a phone results in super slow charging and constant disconnecting/reconnecting. You don't even need the power cord to use this as a USB hub so I'm not sure why it even has additional power input if you can't use it for charging.

I went thru two other brands that were subpar. This brand worked as advertised. USB-B ends fit snug connect without baby issue. It powers 4 devices and feeds into a separate USB hub that connects to a laptop.

It works but I have find out that was having some issues with the power supply. I had to unplug the power to make the USB work correctly. Everything else is working great.

Excellent product, sturdy metal casing and small form factor. Works and looks great wall mounted, unbeatable value.

I have it mounted under my desk for easy access for USB ports for my computer. I can transfer data and charge devices!

There was a definite improvement in response time. Of All my peripherals after changing to this hub.

Works perfectly. It’s the only mountable usb 3.0 hub that I found. Great quality and value.

Seems like a very well made item, sturdy metal case and easy to mount, my only issue is that the power adapter jack doesn't seat all the way into the connector.
By: Doc on 2020-10-02
VERY well made device, metal enclosure and very small. Does not heat up with extended use of external hard drive(s). Very fast, no drivers needed- even on an old WinXP box!

The hub is fine and there are surprisingly few options for something like this. However, take your [total] purchase and add $10. Who's bright idea was it for the extension cable to be 24"? Are you expecting people to mount this hub directly to their computer? Because that's all this cable is good for. Either make the product complete or don't make the product.

When it comes to finding an externally powered USB with actual mounting hardware, it is very slim pickings. This was one of the few products that fell into my requirement for that, though it's a bit of an oversight that this doesn't come with any screws to do so. The negative reviews almost scared me off, but I took my chances and I have received a quality product. All USB ports are in working condition, albeit a tight fit when plugging and unplugging. It does exactly what you'd need a USB hub to do. However, the power supply could definitely use a longer cable. It makes it a bit difficult for cable management when you have only a 3 foot or so cable to do so. The actual hub is made of metal and feels of high quality. Would definitely recommend at this moment in time if you're looking for a hub that you can mount to a desk.

Very happy with the functionality, and performance. Excellent value for dollar.

Solid construction, bright red power LED and pleasant green LEDs for each port.Word of caution if you are plugging in external hard drives, USB sticks, or other peripherals that will be transferring large amounts of data. Backing up files to an old external hard drive last night I was able to achieve sustained transfers of ~30MB/s when connected directly, but plugging the hard drive into this hub (using the same USB port on the computer) slowed the transfer down to ~1MB/s. The hard drive was the only peripheral connected to the hub, and nothing else about my computer setup changed between the two tests.If you want a good looking, hard mounted USB hub, this thing still might be what you're looking for, but you may have performance issues if you are needing to push a lot of data.

I had been using a USB 2.0 hub but upgraded my computer and decided to do the hub at the same time. It has worked perfectly from the moment of installation and I like the LEDs that light up to show it has a good connection. Four stars rather than five only because I'm not sure why anybody would "love" a USB hub.
By: Chris S. on 2017-02-23
I bought this due to the extremely small selection of mountable USB hubs. I've had quite a few instances of losing USB connection to peripheral devices plugged into this hub after waking from a sleep/suspend. I haven't witnessed the same behavior when connecting the peripheral devices to my computer directly. This is a pretty minor inconvenience for me since the hub is mounted on the top of my desk and unplugging/replugging the peripheral device USB is usually enough to jog it back to connectivity. I am using a host O/S of Ubuntu 16.04 and in many cases, a Virtual Box Guest O/S of Ubuntu 16.04 as well.

Works as needed, I really wish the cords were longer as they are 2ft max (I could really see this as an issue with someone trying to minimize cords like I am), but luckily that didn't effect me too much.

Ran into some issues hooking this up to my mac mini but a quick search turned up some help, such as having it plugged into the mac and the power outlet causing the mac to shut down, so just unplugging the power outlet makes it run great. It is fast and sleep, and with double sided tape was able to mount it under my desk for a nice clean look.

Used this to mount under our conference room table to hide some cords and to provide additional usb ports on the opposite end of the table. It works great! Definitely high quality. Just wish it came with it's own mounting screws for the price paid.

I bought this to mount on the back of a cabinet for powering an external HD for my Dish Hopper 3.0. Mounting was easy. The design is very sturdy (not lightweight piece of plastic). I will probably buy another for mounting in a mame cabinet. I can also see this as a great option for mounting under a desk out of the way.

Great hub. Build quality is second to none, individual port LEDs are hepful for troubleshooting, and so far it's been rock solid.

I have this unit mounted upside-down under the shelf of my monitor stand so I have quick access USB ports while working. It is well-built and is working great so far. It is very small and unobtrusive - the front panel with the USB ports has no printing or LED lights. As noted by another reviewer, there are 4 screw holes for mounting but no screws are supplied. I don't understand why so few other USB hubs are mountable as it increases the usefulness when it doesn't have lay flat on a horizontal surface.The only flaw in an otherwise quality unit is the power hookup - the cable length is very short, and the plug itself is lumpy and awkward enough to pretty much guarantee that it will take up more than one outlet. A six or eight foot cord would hardly be a break-the-bank expense and would make the hub easier to use. The USB cable supplied with my unit is 3 feet long - you'll probably be needing a longer one. The LEDs are not obnoxiously bright. The unit supplies power to the ports even when the upstream USB port power is off (ie when the computer is off). However, each port receives a maximum of 900ma so it can't charge high-current draw devices. The USB ports are spaced just slightly under 1/4" apart. This isn't a problem for normal USB plugs but could cause problems with non-cabled devices, eg strangely shaped flash drives.Five stars because of the build quality, the reliability so far, and for having no swoopy curves or unnecessary enclosure flamboyances. Clearly, the money went into the engineering and not the bearded hipster design consultants. It's a small, inconspicuous solid metal box with four USB 3.0 ports that work reliably. That's it.

This is a good little hub, solidly built, and fast.There's not much to tell about this little hub; it's good for an environment where it might get bumped or hit, and can be mounted to ensure it doesn't get knocked across the room when it's bumped or hit!I imagine most people who would be interested in this one, is because it's mountable. Indeed, it has 4 little slots for where screws would go to mount it.Alas, it comes with no screws...But I dug around in my drawers for some screws that would fit it, and eventually was able to mount it where I needed it, and it has been working great ever since!I wish the included cable was a bit longer, so consider getting a USB 3.0 extension cable (I got one from Amazon, works great).Considering you get no screws, a short cable, and only 4 ports, the (current) $34 price tag seems a bit high, but for what it's intended for, it works great.

First Visual Observations:
I was surprised to find a Sunday delivery, the item had been delivered in a padded envelop boxed in the manufacture's box. The item's box itself was a thin white box approximately 8 inches long by 1 1/2 inch high.
The Mini USB 3.0 hub was received packaged neatly in the manufactures box that included:
- Hub’s power supply
- USB 3.0 A to Mini-B cable
- USB 3.0 hub
- User manual
The Mini Hub is small enough that will fit into a small space no bigger than your open hand. The USB 3.0 cable connectors are a tight connection into the USB 3.0 Mini-B port as is the power supply connector needed when using the hub for devices with higher constant power consumption requirements.
Hub Operation:
I used a Windows 8.0/8.1 (ASUS) laptop with the operation of this hub. My basic process with hubs is to connect the USB cable to the hub, then the cable to the host USB port.

The power supply this hub comes with is only for additional power, not for initially powering the hub, the USB 3.0 Type-A to Mini-B cable must be connected as this is the medium for transferring the data.
This is a 4 port USB 3.0 hub, USB 3.0 is backward compatible with USB 2.0/1.1 devices which is what I am using with this particular hub. Backward compatibility means that the hub will operate USB 2.0 devices through its USB 3.0 ports but will only have USB 2.0 data transfer speed (480Mbps).

Recommendation:
Being as small as it is, I would recommend this USB 3.0 4 Port Mini Hub for tight places may require some sort of hub integrated into its equipment or out in the open where multiple port connections need to be made, possible in an office, school or industrial environment. It was operational as soon as I connected it.
Pros:
- Extremely small and capable piece of equipment for running multiple USB data sources
- Easily connects to a Windows system running 8.0/8.1
- Includes LED for power and individual port connection
- Backward compatible with USB versions 2.0/1.1
- Worked right out of the box
Cons:
I found no CONS with this device’s function, worked right out of the box.
Additional Information:
The USB 3.0 Mini Hub’s power supply adapter is labeled:
- Input: 100-240V – 50-60Hz 1.5A
- Output: 5V – 4000mA
