String trimmers have been popular for many years now. These are oftentimes called whipper-snippers or lawn edgers; some are even called by their original trademarked name, Weed-Eater™ or Snapper™. String trimmers come in three choices: gas trimmers, electrical trimmers or cordless string trimmers. Gas-powered string trimmers are the messiest and noisiest. However, they're more portable and more powerful than other types, and are practical if you have a large property to trim. Electric trimmers are easy to maintain, and they are relatively noise-free and clean running. Cordless string trimmers are becoming more popular. Their only drawback is that they have to be charged, but they make up for it because they are extremely portable, without the inconvenience of a cord.
