If it was the product itself it might have been a 5. I ordered this package and the only thing that showed up was the compressor. I called customer service and Daniel was top notch in getting it corrected. The only thing is it went ground delivery. I felt that it was their error and they could have rushed it on the delivery.
Once I got all items it was very easy to set up and start painting. The compressor is very quite when running and you do not need to talk over it. The airbrush is solidly made and easy to change the tips.
I would recommend this company and would buy from them again.
