Bests & Worsts Reviews from Amazon

I have a MityVac MV8000 brake bleeding unit which was purchased less than one year ago. The user's guide clearly states a 1-year warranty on this unit, but the manufacturer's customer service told me they would not honor it because it was purchased from Amazon. They would only honor it if purchased through some other authorized distributor. I'm sure this is not legal, and they're probably counting on people not to pursue this because it's only $30. This is the very first time I've run into a product where my warranty claim has been denied solely based on my purchase location, as if I had bought it off the back of someone's trunk at 2 in the morning.
