I'm a bit of an Android geek, so I had seen this charger floating around the web before I ordered it.
It works exactly as expected. The connections feel solid and secure - anyone who has had a cheaply made charger knows what I mean, because some of them feel like they would just fall out of the phone/computer - but that's not the case at all with this one.
I have a Galaxy Nexus, and there was some concern when it first came out that using some other chargers wouldn't charge it properly. Apparently their output was too low. Because of that, until ordering this, I've only used the Samsung charger it came with, and I was concerned about the Andru charger's ability to charge my phone. However, it turned out fine in the end, and this is fairly subjective, but I think it may charge a bit faster on this one, even.
