Sorry guys but 16 hours on what is supposed to be a brand new unit in my mind is totally unacceptable, seems like one with that much time on it was a returned unit. I get tired of retailers taking back goods and then passing them off as new
Okay guys, let's put a stop to the rumors and hearsay please. The compressors are tested first by the manufacturer and sometimes tested more than once if they encounter anything during assembly. They are then tested by a 3rd party company near the factory to ensure everything is good before the long journey to the US. When they arrive, they are each opened, prepped and tested. And yes of course they are tested "wet" or filled with fluids and lubricant for those unsure what that means.
We asked the importer, Raptor Pneumatics, what they see on every unit for hours, and Todd said they arrive with anything from 3 to 26 hours on the meter. The factory does not reset when the finished product is ready to ship, so these are arriving to us in this range. We then do our testing and prepping. So, 6.5 hours is not used or refurbished, it was simply tested by the factory, importer and us. At least all are honest and don't reset the units once ready to ship. The hour meter will be an accurate number from the time of first assembly. Every unit is thoroughly tested both in manufacturing and again here stateside to ensure all is working as advertised.
If we are shipping out a replacement product of any kind, we generally do extensive testing to make double sure the replacement is perfect. If it were an air rifle, we'd likely put several hundreds of shots through a replacement before sending to test for accuracy, consistency and velocity. With a compressor, we would likely attach it to an air tank and run at least one full cycle to make sure it is doing its job. Shipping is not cheap on these, and we want every customer to be happy.
If the OP would like to make contact with us about his issues, we are still available here, and more than willing to help. We are unaware of what this "rock" could be or where it could be wedged, but our guess is a chunk of Styrofoam from the packaging. We really wish everyone would allow their dealer to address problems first. Often times, as it has here, conclusions are made that are simply untrue. We are available by phone or email, and Raptor Pneumatic are always extremely helpful with any issue or concern on the Omega units.
