The power base is either faulty (which is likely), or it doesnt give the lights enough juice. Either way, the lights started flickering and went dim after only a half hour of use. Whether it was plugged into one of the several wall outlets, or the power bar, it doesnt work. Once I plugged it into my PC I had no issues, but I have limited USB slots and can't have them used by lights.
Overall, I'm disappointed. When they work, they work well, but a faulty or improper power base, makes them almost useless.
If this was $20 I probably wouldn't have thought much of it, but I paid over $60. Not worth it.
