It works just as intended. Audio from my mic was then read loud and clear on the mobile laptop I have.
Well, not all that clear, actually. This interface comes with a fair amount of background noise. It also isn't the most sturdy piece of equipment I've seen; the USB port on the back seems fragile enough to disconnect at a moment's notice after just a few months of use, for example. The buttons on it aren't all that clear at first, but soon didn't matter because they didn't do anything anymore anyway. Also the LED light on it died, which is unfortunate since that's the only indicator whether it's plugged in or not.
All in all, it's a decent interface for its price, but it's not decent enough to do any sort of recording with it. If you're a beginner trying to save as many pennies as you can, that's okay but don't be too cheap on this part; the extra $50 that you'll spend on a decent interface will go a long way. If you're just looking for an interface that links your equipment to a computer, then only then is this for you.
