Yes. Search around. dwike isn't the only one.
I had heard the same thing, but I have not heard any buzzing and from mine, and I drive it everyday. I can't tell you how nice it was to have that thing on there last week for my trip to Charlotte... little to no drone...
from what I've read they have addressed the buzzing noise, and I posted it in another post, but the best place to get these things is advance auto. Right at $100 and no shipping!
