I just had one band break this weekend.....Middle of about a 3hr tattoo it was on a 7 mag. Not while i was tattooing but when i in the rinse cup bammm...needle all the way out.Well i have talked to NATS and they have all ready started repalacing the bands on the new carts to ones that are better quality.Also he will be sending me the replacement bands for the ones i have all ready purchaced. Im still happy with the product and will keep using them.
