Review on Silent Air® X4 Air Pump 2 Outlet by Jessica West

Not as quiet as I expected. A little disappointed. I would have thought it would be quieter given its high price. Update October 2013. VERY VERY UNHAPPY. This pump only got so noisy after 6 months. I can't use it because it makes a lot of noise. I contacted the manufacturer and they told me to buy a repair kit which costs $21 including shipping. He's less than a year old and I've never had to use a pump that's been in service. They should warn you when you buy it that you need to buy a maintenance kit and that the manufacturer will not replace it, just tell you to buy a kit. I will never buy from this company again. Very annoyed
