After watching the presentation on the net and having many physical ailments I decided to take one more gamble and ordered the H machine as it sounded promising. Although it cost about $3200 Canadian, the service was prompt and without incident. So far I'm on the third day of use and the 2 things that leave me guessing is l didn't find a diaphragm in the pitcher and holding the button in for 3-4 secs. As per instructions for standby and off are not necessary.
