We are the only company that does LIVE demonstrations with a microscope at the end of the machine showing that the trichomes are still there. The UltraTrimmer is <bjust like scissors. We’ve proven how well it works at the cannabis cups over the last 5 years and video taped the live demonstrations and the reactions of the people when they look under the microscope at their bud. Other companies don’t do this because it will show what we have been saying for years – they destroy the trichomes and the bud. Our machine is the only machine on the market that simulates scissors. We are OFFICIALLY PATENTED! No other trimmer has our gentle and effective technology.
