We've had 4 Simple Human models through the years and this is the best one yet. Raised off the ground so that the battery compartment doesn't get wet from a puddle on the counter top, easy-on easy-off top to fill pump with soap replacing the threads of the old screw-top model that got caked with dried soap, silicone valve to dispense soap so that it doesn't get stuck, etc., etc. They just keep improving. And of course Simple Human customer service CANNOT be beat.
