I have used this unit 4 times and it has done a fair to good job. It seems to struggle a bid in the heavier weeds. I seem to be getting about 20 min. run time on the batteries, good thing it came with (2). The recharge time for a completely dead batt. is around 3hrs., which I feel is a little excessive. The only real neg. I've found comes with the auto feed on the line. The line is advanced by starting and stopping. So you end up constantly pulling the trigger.
I love my trimmer/edger. I use mine to edge my sidewalks. It's light weight, easy to use, and does a great job. Trim line spools are easy to change! Love it.
I bought the WORX Weed Eater about 2 months ago, and I love the fact it came with two batteries, it always starts, it's not heavy, and the wheels are awesome, we used it to dig dandelions out of the yard, it's got plenty of power, it's just a breeze to work with and my Husband loves it too, we're still on our first spool of cutting line. One of the things we love the most about it is you don't have to wind it with cutting line all you have to do is change spools and away you go. Thank you for making our life easier.
