This is my 2nd AV compressor and this video comes 1.5 yrs after I initially received it. This "update" video was supposed to come after the 1st 6 mnths of use. I decided to wait longer to give a better assesment of its long term durability. IT HAS SURVIVED, I think mostly in part due to the oil i'm using for lubricating the units internals, ROYAL PURPLE Syn.
