Have used the mower once so far and all is good. Engine first started on second pull, but no surprise there it's an Honda. Sometimes the drive for rear roller can be clunky when engaging, I find it's better to pull the lever fully in straight away rather than being more gentle and you don't get the clunk. The mower cuts smoothly and obviously it's a new blade so the cut is second to non. You get the stripes but they are not as prominent as I thought they would be, but this might be due to the weight of the machine. My previous machine was a qualcast cylinder mower with a steel roller so gave better stripes, but the downside to that machine is it didn't cut as well when the grass is too long, hence why I decided to buy the cobra. The Cobra looks well built so we will see how reliable it is by the end of summer. Will try to post an update then.
