My first set lasted 2 weeks

http://hvac-talk.com/vbb/showthread.php?t=170393

about 3 months into my second set, the low side knob stripped out,it would still turn in and out but the valve stayed closed, I never abused it or tightened it with anything other than my thumb and index finger.

I called and described the failure and was told it would be covered under warranty, so I shipped it out to them.

now, after they repaired it, they call and say it will not be covered, and I have to pay $58, so I dont even have the option of having the failed unit shipped back to me so I can run over it with my van and take pictures.

just a word to the wise, avoid this company and their products
