Bests & Worsts Reviews from Amazon

I would rate this a 5 but the design is poor with the new wide mouth. The seal between the bottle and the base is poor at best. My experience has been that if it doesn't leak a first it will later. That said, I just ordered 3 more. I went to the hardware store and bought an o-ring that fit over the mouth of the bottle. It seals between the bottle and the base. Trust me, I did several tests to see why it was leaking out the flower tubes. The poor seal allows air to leak into the bottle and relieve the air/vacuum that holds the water in. The o-ring completes the seal and no leaks.
