I have an 18 volt single string made by Ryobi. It's a dual function number where a twist of the head turns it into a vertical edger. Twist it back for horizontal use.
It's nice and light, well balanced and does ok for edging driveways, sidewalks and fairly light duty roles on low speed. It has a hgh speed setting that guzzles battery but really makes it go. Can do short bursts of heavy trimming in high speed mode.
Low speed I can trim my front and back yard and have enough from a 4Ah battery to use the 18volt blower to clean the driveway etc. All total about 45 minutes of trimming and 15 with the blower.
High speed I can cut through fairly thick grass for about 20 minutes before the same battery demands a refill. You can tell when it gets to near empty because it slows down.
