You only have to hold the cups for long enough to get a good suction going, then they hold in place on their own.

They also sell an in-line air-lock system so you don't need to keep the pump permanently attached...

But no, it's not a micro-pump system. A slightly less expensive option for that over the Brava does exist... I remember seeing something about it, but I can't think of it's name... maybe you can ask up in the pumping section of these forums?
