I stand by this product "I started tattooing with the Eikon Symbeos machine paired with their Hydra needle bars years ago. I’ve always been a fan of Eikon. When I saw their cartridges came out, I bought them up and I’m loving them. I primarily stick with Bishop cartridges but you can feel the difference between Eikon and other carts. The only reason I don’t switch to them entirely, is that they’re new enough to run out of stock often in certain configurations. Once they become more common and have been out for longer, I will likely be buying them a lot more." — ANDREW W. (5/5)
