We tested one of these in our office and for the size of the pump, the flow was very weak. I wouldn't take these over a Nano Stream 6055. Also, the control functions are a bit tricky. I don't know if we got a defective one, but the pump couldn't go from bottom level low to top level high w/out making noise.
The flow is considerably less than a full size stream... with both on max speed, this one only did about 1/4 of the flow while being bigger than a stream 6101
