It’s nice to give a review for product that actually turns out to be exactly as it promises. This Atolla USB hub is exactly what I was looking for. I have several devices, including a microphone headset and several external backup drives. Once the headset is plugged in it overrides the computer speakers. Many times when I forget to unplug it I end up fiddling with the speakers, until sanity takes its course and I realize what the problem is. You’d think I would learn after several times, but well we’re only human. As for the external drives, if I soft-boot or reboot my computer, the computer will read the external drives as if they are the internal drive and not re-boot. Therefore you have to remember to disconnect the two external drives every time you want to reboot. That was a pain as well. And I actually did need some additional USB ports for other uses, having used up the ports on the computer. So I was delighted to see that not only does this have four ports and is designed to sit nicely on your desk next to your computer, but that each port has a switch next to it, so that you can turn it off and on even when it is still connected. Cooler still, when pressed, a blue LED lights up. This way of course I can keep all of these devices plugged in and simply hit the switch. It works perfectly, and is beautifully constructed and looks great. By the way, it also has another port on the side, specifically for charging. It’s a nice addition, though the other ports will charge devices as well. I’m not a big tech nerd, but I believe the difference is that the charge port may have a power limiter or fuse. Something honestly that is truly not a problem, unless you’re using the port to charge a power tool or a Toyota Echo! Nice to get something, as I said that meets if not exceeds expectations.
