Very good for its price. It struggled to cut thick but green grass at first, but it cuts it in the end. It is powerful, but the factory-installed string is thin. Only 1.6 mm. Of course, with a modification, you can use a thicker string. Make a small hole in the base of the spool to pass the end of the string through, then wrap the string in the direction of the arrow. I used a 2 mm string and saw a tremendous improvement. It can easily handle 3 mm as well

It cuts some grass. It doesn't work or doesn't cut thicker weeds at all, the wire underneath keeps getting cut.
