 Good for USB 2.0; Bad for USB 1.1 November 18, 2008
Pro: With the rebate, this is an excellent price for a USB 2.0 hub. I've had up to 6 USB 2.0 devices connected to it without any problems. I've had it for almost a year.
Con: Does not work well with USB 1.1 devices. I connected a USB 1.1 scanner to the hub. For about one out of every 6 scans, the scanner will lock up and I have to reboot the PC to restart it. If I connect the USB 1.1 scanner through a USB 1.1 hub, then it locks up about once every 25 scans. In any case, ALL the USB devices slow down significantly when the USB 1.1 scanner was connected - It didn't matter whether or not I was using the scanner. My USB 1.1 printer also causes the slowdown. My solution was to wire my USB 1.1 hub directly to my PC and have it only drive my USB 1.1 devices.
As a side note, disconnecting the USB 1.1 device while the PC was on did not improve the speed. The USB 1.1 device had to be disconnected before the PC is powered on to get maximum speed.
One Complaint November 17, 2008
I only have one complaint about this hub and that is that when I shut down or restart my computer the hub will cut power to all ports even though it is a wall powered hub. When this happens, my hard drive that is connected to it abruptly shut off. I have a few different hubs and this is the only one that does that. I don't think that it is damaging to the hard drive because nothing is being read from it or written to it but I just don't like the sound of the heads parking so quickly. I still think it is worth buying!
 Works fine. November 16, 2008
I needed additional USB ports and researched USB hubs. This one got good reviews at a reasonable price. Most cheaper ones had issues that I didn't want to have to hassle with. I connected this as the main hub for direct use items like printers and external hard drives, and use my previous hub as the secondary for gps, bluetooth, flash drives, etc. I have had no connection problems at all. This also allowed me to have my wireless keyboard/mouse usb connection closer to my work surface. Because of free shipping, this hub was cheaper than one at another source with rebates. My experiences with Amazon and Amazon sellers has been excellent and influenced this purchase.
Small size...works fine November 16, 2008
This will be a simple review since everything works as it should. I haven't had any problems with any of the 7 devices connected to it. Unlike my old Belkin hub, this one stays nice and cool.
Could be better November 13, 2008
I bought this a month ago as my first USB hub, and overall I am very happy with it. The device is small and attractive and gets the job done. However I do have a couple qualms about the design. First, the provided USB cord connects straight on into the back of the unit, but the power adapter connects at a 90* angle, so they don't lie parallel to each other. Second, the device does not indicate if it is running on USB power or wall power. And finally, the indicator lights below each port are always on, so they have no function. I would have expected them to come on green when something is plugged in, flash with activity, and maybe turn red when there is a malfunction. Overall though, its small and works, which are my primary concerns.
