My new Aeropress works perfectly. My previous two have been purchased from Amazon of course! I spotted your site when searching google for Aeropress. Your price was the best I have seen and the delivery was up to the mark. This is my third Aeropress. The first lasted 2.5 years, the second only about 1 year. I have unsuccessfully tried to fix problems with new plunger rubbers but this did not prove to be satisfactory. The new one you provided seems great. Aeropress has changed my life. The quality of the coffee is unbelievable. The perfect coffee for me is M&S Espresso strength 5. I will know where to come next time. A very happy customer. Regards...……………...Alan Power (Warwick)
