Similar experience to the first reviewer, ie the line breaks. In my case, after 15 -20 seconds of usage, even though I have wound the line properly! Is it the line [reel] or the autofeed, I dont know.
It cuts well and seems durable - but after today's experience where it took me 50 mins do what normally takes me 5 mins, I've had enough! This is the third reel, in some 12-15 strims.
I would mention that I've used a strimmer for some 8 years, so not a novice. This is a bad design, I feel. A decent cut after much frustration and so much wasted time is hardly worth it.
Do not buy!
