Yes, 7 years! I have had the same Worx GT Trimmer/edger for 7 years. Same two batteries and all. The only thing we have had to replace was the string trimmer cover and of course the string. I must have a small yard, nope, 2 acres at my current house for the past 3 years and 1/4 acre at the previous house. With a 100' long driveway and a lot of landscaping, shed, chicken coupe, fenced in garden and play set we put it to work hard when we trim and cut. Waiting for this thing to die so I can buy one of the new ones. The extra battery comes into play most cutting days.
The only thing I think they can improve is the wheels used when edging. The clump up quickly with the grass trimmings and then the string doesn't go as low as it did when clean. I have to stop and scrape off the trimmings every so often. I am sure they can put on some self-cleaning wheels on it with no extra cost. I just watched one of their commercials and you can see it happening within the commercial.
Bottom Line: Yes, I would recommend this to a friend
