Ego Power+ ST1521S 15-inch string trimmer review: design and build quality I was impressed with the overall build quality of the Ego Power+ ST1520S, which requires just eight screws to assemble.

If you’re looking for a low-maintenance, frustration-free, eco-friendly trimmer, the Ego String Trimmer gets the job done right. This machine rivals even the toughest gas-powered weed whackers.
