What is the best brand of needle cartridges to use?

Hi Terry, with equipment it always comes down to your own preferences and how you get on with certain products. The major needle cartridge manufacturers consistently offer good quality and a wide range of configurations. We can highly recommend the TATSoul Envy Gen 2 cartridges, as they use the best quality steel for the needles and the quality control is very good. The innovative finger ledge also allows the cartridge to be held directly for even better control of the needles.
