The Trim'R-Matic goes to work for you with an oscillating blade and two blades on either side that it traps the leaves of the plant between. Using the handy built-in speed controller the user can change the speed of the trimmer from slow to high and it also works as the off switch. The Trim'R-Matic runs on 120v or 240v and plugs straight into the wall or power strip which means that there is no heavy power supply to carry around making trimming all that much easier. The benefits of using an automatic trimmer are numerous. One hard carrying case and 1 oz of oil included.
