Here's another potentially helpful note to people trying to 'match' the output of your Buzz to another mod you've grown used to:
Remember to consider the ohms of the atty your using as it related to the stated voltage of your other mod. For example, I was trying to match the output of my Prodigy V1 and V2 by dialing in at around 5.1 - 5.3 volts on my Buzz, and not getting the same results. After much tinkering, I finally realized that the Prodigy units have been tested under load with a 901 atomizer at 5.2 - 5.3 volts. A 901 atty runs at almost 3.4 ohms. So, the actual voltage I was getting on my Prodigy units is probably more like 5.6 - 5.7 volts with the 510 cartomizers that I've grown so used to, as they run at about 2.8 - 3 ohms.
How did I discover this? The Buzz taught me. Then, after lots of head bashing, my logic and math finally caught up. ;-)
