New Edy heads, poor quality control what to do

All good points above but, I will never buy an Eddy product again after being very disapointed in Eddies Customer service for a badly manufactured set of new out of the box RPM heads...I paid another $400.00 to have them cleaned & checked and it's a good thing I did. I was happy to buy "bolt on, made in America" and pay a bit more thinking I was getting quality and tech support....WRONG!
