This thing was an absolute nightmare from start to finish. Assembly was so frustrating that I gave up pretty early and had my dad come over to help. He struggled with it, too. The instructions are terrible, like, basically useless. We ended up finding a video on YouTube to figure out how to piece it together. That should've been my first warning sign, but I've always had a hard time recognizing red flags. Once it was finally assembled and batteries charged, I tested it on my front yard, which is a few patches of different kinds of grass with dandelions mixed in. Nothing overgrown or out of control by any means. My dad had installed the saw blade attachment, which I originally thought was crazy unnecessary for what I'd be cutting. It was not at all crazy or unnecessary. That saw blade attachment STRUGGLED to cut the dandelions, and only half cut the grass. It was nuts how poorly this thing did. The biggest reason this thing sucked so much was that the wheels and little guard-rail-things around it pushed whatever vegetation down before the blade could ever get to it. You have to go over the same area fifteen times before you mostly get everything cut evenly. Another reason it sucked was the narrow path it had when cutting. You have maybe three or four inches getting cut by the blade at a time, and when you factor in that half of that is being pushed down and out of the way of the blade entirely, it only leaves you with maybe an inch and a half wide path actually getting cut. Of yeah, and half the time, when the saw blade actually did make contact with the dandelions, it would take a couple of passes to actually cut all the way through the stem, not just halfway. And that was with the blade straight out of the box. The battery life was terrible, too. I went through both fully charged batteries in less than thirty minutes of sparse dandelions. Insane. I know this thing is cheap, I mean, that's why I bought it in the first place, but your money would be better spent finding a normal, used weed eater and going that route instead. This one is a joke. Oh yeah, and the battery is a nightmare to take off the mower thing. It's supposed to be "press the button and slide it off", but, much like everything else about this thing, it just doesn't work like it's supposed to, and your job is made ten times harder as a result.
