Hello, Shayan! Thanks for the Zero Blade review. I'm sorry to hear if there's any disappointment here! The Zero Blade should be trimming at 0.2mm, which is about the height of two pieces of paper stacked on top of each other. If you feel that your Zero Blade isn't performing as it should, please don't hesitate to reach out to us at Support@BrioPG.com - we're always happy to help!
