The product arrived on time. This is a good product for the price, especially with the activated charcoal filter included. The only downside is the air release valve, which is not a "pusher" but a "screw cap" to release trapped air. Second review: (2/21/19) My device exploded on 2/18/19 after just over a month of use. So I reinstalled my old one which was replaced with this unit which has been in use for about 10 years. My rating for this device has now been downgraded to 1 star. Not worth buying. See photo.
