I read from time to time about people worried about the Buzz leaking juice around the top and especially the screw. I have one of the first ones that were produced, a gold one, so yesterday I did a test to find out once and for all if it leaked. I removed the top cap, leaving the wire attached, layed it on it's side and put tape around the cap to form a reservoir. I filled the reservoir with juce and let it sit for 4 hrs. then repeated the step with water because water is thinner and more likely to leak. The water was left in it for 4 hrs. too. There wasn't one smidgen or iota of water or juice that got from one side to the other. I feel safe now knowing it won't leak and I'm very happy it's back in service for me to use.
