Just received my new "Owen" tattoo machine. Took a while to get to the UK due to postal strikes. Upon opening the package I was pleased with the high quality of this machin, and the low noise,and vibration when using it. I have two Stigma machines now and I use Stigma cartridges with both, have never had a problem with either, and they always do a great job no matter what. I highly recommend any Stigma product.
