 Does its job, and does it well August 29, 2010

It's basically impossible to get excited over a USB cable, so I won't be using any superlatives when describing this item.
It simply allows you to connect a USB device in another part of a room, further away from a computer than you would be able with regular USB cables. When the computer is on, a red LED will light up inside the large connector at one end to indicate it is working.
Packaging is minimal and instructions are non-existent, but you really don't need them. Simply connect this cable to your computer, and the desired device to the other end. You can even connect a USB hub to this, and the devices to the hub, and the computer will see them all -- in my case, it allowed me to place my three printers on the opposite side of the room where my computer is, freeing my desk and the area immediately around it for other purposes.
Definitely worth the money.
 Very handy August 26, 2010

I got this cable to extend a wireless usb receiver into my bedroom from the computer in my home office. I haven't had any signal problems and it's perfectly flexable enough to get in the right position. It's active, so if you wanted to you could add a second one to make it extend even further.
Works Great! August 10, 2010

Plugged it in to my MacBook Pro Laptop / Nikon D2X and it works great. In fact, it seems like the transfers are even faster than with my standard 10 ft USB cable. This is an excellent product, just what I've been looking for, for tethered photography.
Great for Extending USB Connections Between Computers July 31, 2010

I connect my laptop to my desktop to transfer files between the two, using a Belkin Easy Transfer USB2 cable for that purpose (http://www.amazon.com/gp/product/B002PAR0AQ/ref=oss_product). This Tripp Lite cable, which as others have pointed out is actually a single port hub, if you will, makes that process easier for me as I now have a port near the file cabinet on which the laptop rests while at home. The extension cable installed quickly and automatically under Windows 7, and surprisingly transfers between the computers are a little faster using this cable than without it, according to LapLink (the transfer software). Excellent choice if you have a need for such a product.
In reality, its a 1 port active hub and 16 foot extension July 19, 2010

USB is a complicated protocol so lets get to simplification.
USB Power is 5V +/- 0.5 V and 500 mA current. About 2.5 watts of power are available. The reason alot of external usb hubs come with a wall wart is if you have 4 devices each drawing 500 ma, that's more than the computer gives you, and something will have to be removed without external power. The wallwart is usually a 5.5V, 2A or less power supply so that each usb port can have the full 500ma on a 4 port hub, neglecting the data rates which are transparently handled on usb 2.0
As for cables, the standard USB cable was defined as 6 feet, just like power cords are 6 feet most commonly. Following the power cord tradition, USB offered a 10 foot extension for a maximum distance of 16 feet before the signal degraded too much to be usable. Hence you'll find 10 foot PASSIVE extension cables in the $9 price range, which you can combine with your existing 6 foot cable for 16 feet total.
The real advantage here is there is a low power (<50mA) "1 port" hub at the end of this 16 foot extension - that regenerates your high speed usb signals for your device. It does steal some power, allowing 450 mA for the device, but most devices don't complain about not having the full 500 mA to themselves with a few exceptions for battery containing devices that must charge and disk drives that get their power from the usb cable.
Now at the end of this you can put another 10 foot extension and 6 foot cable for 32 feet of total length if needed for outdoor or room to room usb. It's a great product to get around the 10 foot extension common length limit.
Often I have "usb radio fobs" or radio transmitters for wireless keyboards. By putting them high up the wall and onto the ceiling, I can carry the wireless device that works with the fob a long ways away - much further than if the fob is hidden down behind the pc chassis on the floor. The 16 feet gives me adequate length to go over then up the wall and into the center of the room for best coverage.
Overall I much prefer the active extension cable to the passive since the signal received at the PC will be just as good as if the device were plugged directly in. Tripp Lite uses a well shielded cable for exceptional quality and very low signal loss in the run back to the PC. While priced more, it is an active hub and you get that added value from the product.
