I really wanted this device to work well. I had problems with it continually disconnecting and reconnecting. I thought it might have been because I didn't have the power cord attached and it wasn't getting enough power from the USB, but plugging in the power adapter didn't help.It's been going on since I got the product and it's very annoying to constantly hear the alert on Windows when the devices connect and reconnect -- literally hundreds of time per hour! I didn't even realize there was a time limit for returns, luckily I signed on today and saw I had on more day to return it.I thought about exchanging it, but then I read the other reviews on here, and I don't want to go through the hassle again. I think I'll just find another more reliable brand.I like the construction of the device--it looks and feels nice. But let's face it, if a USB hub doesn't work, it doesn't matter what it looks like. It needs to work.
