Sorry dont post much just come here to read...Due to work,obligations and lack of time I have not been able to get out but once in the past year.My problem is I was one of the lucky ones to get the ATpro upon release with the preorder when they first came out and have a very early s/n on my unit...Now work has slowed and Im ready to give it my all but am worried I have a defective unit and will have trouble with leakage and falsing...My question is should I send it in and get it checked before going out or just wait to see if it messes up?
