Four-Port USB 2.0 Ultra Mini Hub lets you connect up to four USB devices to a single USB port on a PC, Mac or laptop. Certified by the USB-IF to support hi-speed data transmission rates up to 480Mbps, mini hub is perfect for both the desktop and mobile user. Self-stored cable is the size of a 3/8" thick credit card. For the desktop user, a provided extension cable puts the hub within easy reach wherever the PC is located. While the hub will function perfectly in virtually all cases without needing external power, a provided compact, international AC adapter (110/220V) connects an especially power hungry device. Hub is backwards compatible so it will function with USB 1.1 peripherals as well as USB 2.0 devices.

    The hub I got doesn t look like the one in the picture. This one is silver with a blue light in the middle of it and all four of the ports are on one side. The one I got works fine. It is ideal for a laptop. Just in case you are wondering thr cord which attaches to the computer IS that short.

    The item pictured is not what you receive. As a previous reviewer has noted, you get a long thin silver hub with all of the ports on one side. It looks very much (but not quite exactly) like the USB hub in this kit: Tripp Lite PK3022ET Notebook/Laptop Peripheral Kit with Network Cable/Mouse/USB Hub. It s about 3.5"L x 1.5"W x 0.5"H.

    Although the description of this item includes Macs, the packaging says that the system requirements are Windows 98SE/2000/ME/XP. (No Mac, and no Vista) It does have a dual-voltage power cord and a 4ft extension cable as advertised. It is the same item number (U222-004-R). The packaging doesn t say anything about being USB 2.0 "certified", only that it s USB 1.1 and 2.0 compatible.

    In fact, it doesn t work on my Mac G5 desktop. Since the hub is not supported for Macs, this is not surprising. I can use it for the printer, and if I plug in an iPod it does charge it (slowly). However, the iPod is not reliably visible from iTunes. Also, the thumb drive that works on both the laptop and the Mac when directly connected was unreadable when plugged into this hub connected to the Mac.

    The blue light on the top is VERY bright if you look directly at it. I was looking at the top of the unit when I plugged it in and I was seeing spots for minutes after that.

    It works OK on the Windows (XP) laptop that I have for work. Since that was half of the reason I bought it, I suppose I ll keep it. At less than $25, it s very cheap, after all. I wouldn t even consider paying the full list price ($49.99) for this device. It is just not worth it.

    What can you say? It is a device that fans out 4 outputs, from 1 input.

    And I thought, for the most part that; A hub is a hub is a hub, right?

    Given that Tripp lite is a well known brand; this must be a good product, right?

    While I have used these without any issues personally, and they seemed to be an average USB hub.
    (Nothing special, but also nothing problematic).

    We bought about 15 of these USB hubs (maybe 20), and for the most part, they worked okay.

    However, a couple of my end users had overheating problems.

    1. an end user was charging his mp3 player.
    He smelled a burning smell, and noticed the hub s lights were out.
    The hub itself was slightly bulged, (like it had developed a blister the size of a quarter)
    and the hub felt hot.
    He removed power. The hub had died.
    We discarded the hub.

    2. A second end user was using the hub to transfer data, and it just died.
    It too had an overheating problem; being warm/hot to the touch.
    That hub was also trashed.

    The remaining usb hubs are still in use; a few years later.

    Looking at the percentages, I d have to say it is an "average" USB hub.

    Because it is small, I can understand that overheating could become an issue.

    The usb chassis should have had more air holes/slots, for cooling.

    The unit has a 3 year warranty.

    But that is more for marketing, than for the end user s piece of mind.

    Who would spend 8 or 10 bucks to ship a warrantied item back?
    And then have the company send the same type product [and it might even be refurbished]

    Something this cheap, you would buy a new unit and pitch the old; regardless of any warranty.
