- Weight: The weight of the trimmer can be important if you will be using it for extended periods of time. A lighter trimmer will be easier to use and maneuver.
- Price: Cordless hedge trimmers can range in price from around $100 to $300. The price will depend on the features and specifications of the trimmer.
