Alternative trimmers of the same price range

There are other trimmers which are fairly similar to the Joe TRJ 600C in terms of price range and function. One choice is the Earthwise CST00012 18-Volt 12-Inch Cordless String Trimmer and the Greenworks 21212 13-Inch 4 Amp Electric String Trimmer/Edger with Telescoping Handle. Also take a look at our review on the Black & Decker Grass hog which can also be transformed into an edger.

20-Volt Lithium Ion Battery

The Trimmer draws power from a 20-volt lithium ion battery. The design allows for easier trimming of gardens and lawns, as it eliminates the need for wires which are a common source of hassle while on the job. You do not have to worry about tripping over a wire, getting entangled in it, or pulling it from the socket. The lithium ion battery on this efficient trimmer is also lighter than the nickel cadmium batteries on usual cordless trimmers, which gives way for easier handling and use. The battery only takes an hour to fully charge up, letting you get to work faster.

Quick and Easy Trimming with Auto-Feed Line Technology

Lending to the efficiency of the TRJ 600C trimmer is the auto-feed line system, which allows for seamless and quick cutting. The head of this trimmer is also capable of turning 90 degrees due to the Press-N-Groom cutting design. With this system, specific tasks are made easier, like weeding and edging. Depending on what you need or what you want, this trimmer makes it achievable and easier
