Negative Positive
Title: The older model is more reliable.
Review: Mine worked for a while, but then seemed to start to stick, which made it impossible to pump anymore. I tried soaking the entire mechanism several times in soap and water, but it still doesn't work. I initally liked the clicking feature and sleeker design of this model, but have gone back to using the old version, since this one stopped working.
Is the review positive or negative?
