I'm still fairly early in my career, but in the 3 years I've been tattooing, I've bot and used LOADS of different needle brands and these V2's are by far the best. I love the grip on the carts, I love that they show the number of the needle on the actual cartridge. I have yet to have one that has any defects. They're solid needles, they're well made, and I plan on ordering from them, for a long time.
