Doesn't vibrate much at all. I made sure I got the one with the twin diaphragms in the pump. Make a fair bit of noise as you'd expect.
Motherboard with massive ground planes (which is fine when wave soldering...) and lead-free solder = mediocre results. Just like a regular iron, it takes way too long to heat up. I did manage to pull off a few heavy duty inductors with it though %-B
Works great for regular stuff. If it's a job you can do with a soldering iron and a regular solder sucker, you can do it with this, but its much easier
Overall, it works fine, but I wouldn't classify it as a "Must Have" tool. You can get by with a $10 manual sucker for the odd occasion when you need to clear some through holes or whatever.
Tried to get a video of it in action but its really hard on my (currently messy) small workbench with the camera between you and the tools. Battery in the cam went dead before I got any usable footage. I have some time off next week for the holidays so I'll see if I can get back into taking some vids.
