1 out of 5 eggsSave your money

Pros: The computer setup the drivers when I plugged it in.

Cons: Everything else. About 17-18 times out of twenty, when I would plug "ANYTHING" into it, the computer never saw that it had been plugged in. Phone, MP3 player, mouse, didn't matter what. It was a shame too, because I have never seen a bad product from Tripp-Lite before. Had purchased 3 of these and none of them worked as they were suppose to.

Other Thoughts: If you need power supporting your USB hub at an extended length from your computer, say 20 feet, then this is a waste of your money.

Other Thoughts: dont do it

5 out of 5 eggsmost compact design

Pros: Very small, lightweight and reliable. Optional power supply a plus. Designed for travel but works like any other hub.

Cons: None for what it is.

Other Thoughts: I bought this exactly 1 year and 3 months ago for a friend who wanted another port for his iMac which only had 2 that were already in use. He didn't want another device on his desk if possible so I plugged it into the back of the screen and did not connect the power supply. And even though it dangles off the back, it is stable enough and cannot be seen from the front - which he liked. He uses it to plug his external Macally 2.5" USB HD (self-powered) which he often travels with. He has had no problems with it to this day.

1 out of 5 eggsall around piece of junk

Pros: it works the first few weeks

Cons: the hub began installing and uninstalling itself repeatedly and no longer functions. 30 day warranty for a product that lasts 32 days. its out of warranty so i opened it up. the center screw that attaches the two halves of the device smashed the usb cable and exposed copper wire causing a short. i believe that is the problem. incompetent assembly line. this product simply blows. actual "in-service" time was less than 3 weeks.

Other Thoughts: its JUNK, do not waste your money

5 out of 5 eggsGreat compact USB hub

Pros: I have purchased 2 of these, one for use on my desk to make USB ports more accessible, and the other is not even hooked to a computer - I just use it to charge MP3 players. Both work great and have not had any issues.

This is one of the smallest 4 port USB 2.0 hubs I have seen. It has its own power source, which is handy for the second use I named above or when your PC is off.

Cons: Ports are spaced pretty close together, so if you have a USB plug that is very much bigger than the port itself, you will not be able to use all 4 ports. This is to be expected on a compact USB hub, and I don't really consider it a con.

4 out of 5 eggsa little weird

Pros: Seems to work well once powered. Small form factor. Came with extension USB cable and power supply (good thing it came with power supply, see Cons).

Cons: I don't know if this is due to my USB port, the Trifecta memory or the hub itself, but I suspect the hub: When not powered and I plug in my Trifecta memory 2GB memory, an mp3 will appear to copy over fine, but the data is scrambled and either won't play, or barely plays (like 2 seconds of it). I tried smaller mp3 files, renaming the files, all 4 ports, etc. Copying back to my pc from memory stick, same thing. Once powered though, the device works fine. Memory stick directly on PC worked fine too.

Other Thoughts: There appear to be a few different devices with this exact form factor by different brands. I think this is the best one due to the inclusion of the cords. A previous other brand I tried (same form factor) overheated and eventually became erratic. I'll post here if this one dies.

5 out of 5 eggsSelf-powered USB hub

Pros: I was worried this hub wouldn't work with Vista since it isn't on the OS list but it plugged in and worked right away. Cool.

Cons: None

Other Thoughts: I ordered this hub yesterday and I got it today. Newegg is now at the top of my online electronic suppliers.

5 out of 5 eggsNice little powered USB hub

Pros: Compact, USB connector folds under to take less room. Comes with a 110 volt power supply and USB M/F extension cable.

Cons: None.

Other Thoughts: This is a nice hub, you can tell it's geared toward a laptop user. It's small, which I find to be an advantage. I am using it to add extra USB ports to a server and was concerned about the short cable. When I opened the package I was pleasantly surprised to find a 4 foot USB male to female extension cable. The price for this powered USB hub is exceptional. Because it has it's own power it can be used to charge USB devices when not connected to a PC. LED comes on briefly when first connected, then lights when there's a active USB device connected to the hub.

5 out of 5 eggsVery good after initial pressure applied

Pros: Assists my external CD Drive in power as well as adds a USB connection site away my mousing area And has a little blue light.

Cons: When I first tried to assemble it, it would not come together, I tried several times then one day pushed harder and it fit together no problem. This was the only thing.
