I love it!! Used it ass soon as I took it out of the box easy to assemble.  Once you get used to where the line is it's a breeze from there. I hit the concrete a couple of times at first by the second section it looked like I had hired someone to do it.  Where the were thick patches I lifted blade and gently put it back down and that managed well. Great product does exactly what other comments said it would!! Very pleased would buy again. The only noise it made was me against concrete LOL
