Fully functional and exceptionally well constructed
on October 9, 2013
Before proceeding I want to disclose that I received a review sample from the manufacturer. Another point I need to make is some models on this page come with switches and indicator lights. The sample I received is the same part number as what is listed in the product details for HB-B4U3, so if you read reviews that discuss switches or lights that is not the model I am reviewing.
I tested this on an older Dell PC and an Acer netbook, both running Windows XP and it worked perfectly on both. More importantly, not only did this hub connect to my Galaxy Note II phone for data transfers, but it also charged it. Not all hubs that I have tested in the past would charge the phone.
This hub operated perfectly with all four ports filled (a mouse, a high-speed wireless G adapter, my phone and a camera. I used the wireless G adapter to route between two networks with my built-in wireless adapter while downloading photos from the camera and transferring files from my phone. All this over the slower USB 2.0 port on my computer. Had I been equipped with USB 3.0 it would have been even faster, so I am impressed with the hub's electrical level construction.
The physical hub is also impressive. It has a plastic case with an an aluminum top. That not only provides a sturdier housing than many of the plastic body hubs on the market, but I am sure it also reduces radio frequency interference (I have no means to measure that aspect so am guessing.) Another thing about the physical construction that impressed me is the heavy gauge cable (a short pigtail, actually) and the strain reliefs at both the USB and hub ends. Sabrent did not cut any corners. The icing on the cake is the ports all were within tight tolerances because they were not too tight or loose when inserting or removing cables - and I tried a variety of them, both cheap and of higher quality. The USB plug end perfectly mated with both my Dell and Acer.
Overall this is a sturdy hub that provides a compact way to connect up to four extra devices into your computer. It will also function as a four port charger for phones and tablets in a pinch, but I am not sure I would use it in that capacity because dedicated chargers have overload prevention circuits that this lacks. My honest opinion is this is one of the best hubs that I have tested.
