This new and improved model has a rounder look with a new soft yellow color. The vacuum regulator has been relocated to the side to allow for easy, one-handed control. This is a good pump for short-term separation. The auto-cycling motor is nice so you do not have to press any buttons to release the pressure. It operates with it's AC transformer or 2 AA batteries (not included). It works with any standard collection container and comes with a 90 day limited warranty.
