SABRENT 4 Port Portable USB 2.0 Hub (9.5" Cable) for Ultra Book, MacBook Air, Windows 8 Tablet PC (HB-MCRM)

Had for a few years and still works just fine. Would recommend.

I bought this device in 2020, and it did the job well. When it started to fail, I replaced it with one that's identical, expecting it to be serviceable for at least a short time. Well, it worked until it didn't. I got 5 months out of it, and in the meantime it caused me a lot of problems and time. The issues I was having surely couldn't be related to the new hub. Wrong! I would not recommend its purchase, and as time moves marches on, everything is becoming more and more junky.

It seems like there are more and more USB devices I need to use with my computer. Just today, I had a USB mouse, a label printer and a Bluetooth adapter plugged into my laptop. That took up all 3 of my USB ports and left no room for my external portable USB speaker. And my Surface Pro only has one USB port! That's why I was delighted to have the opportunity to review this slim, bar-style USB hub.I was surprised to see just how slim and lightweight this hub is! That's a big plus when traveling with my Surface Pro because this will fit into my small carrying case. It plugs into a USB port and gives you three additional ports for a total of 4 ports from one. It doesn't need an external power supply and there are no drivers to install because it's plug and play. The drivers are installed the first time you plug it in.I plugged in 4 different USB devices and all ports worked perfectly however, I did get a message on my Kindle screen that it was plugged into a low power port and therefor wouldn't charge while in use and would charge slowly when not in use. Because the power from one USB port is divided into 4 ports, you should assume that it won't charge any device very quickly, but the devices can be used while plugged into this hub.Although this is USB 2.0 rather than the faster USB 3.0, it will still work in a USB 3.0 port - just not at USB 3.0 speeds.NOTE: Anyone with a computer will find this to be very handy and even though I was provided a sample of this hub for reviewing purposes, I liked it so much I just ordered 3 more for other family members.

UPDATE: I'm "correcting" my earlier critical review and upgrading the rating to 4 stars. I did just discover "mounting holes" in the bottom of the unit that will allow it to be anchored to a wall with screws so my concerns have lessened about the unit potentially flapping around and the usb wires possibly pulling out under the strain of the movement of the hub. So I will give credit in the design that this issue has been addressed and my negative review earlier (see below) was a little premature. I'll have to admit that with all the cables attached to it, one runs the risk of disconnecting a device by turning it over to inspect - as I actually realize that this was a feature (the underside holes) when I just went back and read another Amazon review and then gently felt under the unit and discovered the holes! So my mistake - the unit is functional. One thing I do like is that it is "unidirectional" - all usb plugs attach in the same direction so less space is required. For example, Monoprice makes a 12 and 24 port usb-2 hub that is round - looks like a flying saucer as one person described. That works for some people but if you are desk-space-constrained at all then the circular style Monoprice hub ( http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=6435&seq=1&format=2 ) takes up ton of space and is more of a hassle to use. This flat design of the Amazon- Sabrent hub is more convenient - especially when one like myself who is sometimes a little slow on the uptake (haha) finally figures out how to anchor the thing down! I might add that I still am bothered (as described below) by the dinky and almost useless little 12 inch connecting usb cable that is included with the unit - I ended up using a longer cable that I already had in its place to daisy chain this unit to another usb hub I use. Besides that one issue, the thing works fine(MY "OLD" MORE CRITICAL REVIEW IS BELOW):For a while I've been on the fence about this but have finally decided to return it after having it for almost 3 weeks (that one month window is almost expired!) All the ports work - problem is that I'd like a way to anchor it better to the table surface - might get some heavy duty 3M double sided tape - they should include this with the order perhaps? Otherwise it just floats arond at the whim of the USB cables attached to it and can lean and almost become unstable because of pressure exerted upon it by various USB cables. Has the risk of a cable detaching and then you get the alarm that "external disc was not removed properly could cause damage and other fears." Talk about causing some panic combined with anger! Another problem: Sabrent really cheaped out on the "connecting" usb cord - ridiculously short - in fact it almost angers me that they had the temerity to insult us with such a short cord. Perhaps a foot in length? 12 inches? Insane. It therefole only functions when attached as a quasi extention cord to another usb hub - it doesn't function well "on it's own and the cord isn't long enough to directly attach it to my iMac. I thought I could get by with this but as I just mistakenly disconnected a disk for a moment I realized that this thing is not worth keeping. Funny how I've not really thought about the functionality and usefulness of this item until I sat down to do some reviews out of a sense of obligation to the Amazon community if you will - where so many great people take the time to give their sincere and unbiased (haha just kidding - we all have our biases - only mine are correct haha) reviews. But until I started reviewing this item I thought I could live with it , but now I realize that it is more of a problem that I had previously acknowledged to myself and am returning. At first I was just so pleased to have the extra usb space capacity I sort of ignored all the negatives. So in summary, thanks Amazon reviews for letting me look internally to realize I don't like this usb hub! And thanks to me for writing this review for others and ultimately for the sake of myself and my own product self awareness and consciousness! haha

This was a great choice for all my usb cables. I got rid of 2 other usb port boxes. It works perfect.I use it for my printers, scanners, tablet, mouse, etc.

I bought this in 2016 and it was set up to our main computer in the print shop for the past nine years, active everyday even if the computer was shut down.It just died on us yesterday. It worked great having almost all the ports hooked up to an individual printer (ten printers in total).If you're wondering about a stable connection or how long it will last, you won't be disappointed.
