I had one and it was a POS. Got rid of it after I had to rebuild the piston for the THIRD time after a grand total of 16 hours of use. Don’t waste your money on these.
When you can get a new GX CS4 that is quieter, quicker, runs a 5 hour duty cycle filling tanks and will fill to 400 Bar for the same price, or less, there's not much appeal to this one!
