I purchased the 6L milking machine about 7 weeks ago. It worked pretty well for about a month and then started losing suction. I tried tightening up everything and removing parts to make sure it wasn't in the bucket. The problem is in the pulsation machine. I got on the website chat (I started as number 60 in the queue and had to wait about an hour) then a person asked me to send a video of it not working, which I did in about 5 minutes. Then they said they would get back to me. Two days later they said "the engineers say you should tighten up the fittings." I told them I had done that and I needed a new machine. Then 2 more days went by and they offered me $20.00 to keep it and go away. I said no, 2 days later they told me returning it was a very complicated procedure and would I please take $39.00 and keep the machine. At this point I am done with this rip off company. I am purchasing a real machine, made to order in the US and spending a lot more. I am fine with that because I want a machine that works and a company that backs it up. You might get lucky and get one that works but if you don't...well would you take $39.00?
