Have not purchased from Amazon this device. Like the other recessions I can only confirm that the assembly without (missing) instructions is quite a chore to determine where what belongs where such. In addition to that a Besfestigung the wheels was not right ... firmly after repeated removal and installation, I had to realize that a screw had been wound up and the thread was worn. No problem: Since it is a metric screw, I found an appropriate in my stash. The first time you use the device worked satisfactorily. Only the plastic lip on the lower cross strut broke up and crumbled into small pieces. The benefits of the collecting basket I put also questioned, because he can quickly run or will not be filled because the grass sometimes jammed in the machine. Ultimately, I scarify without the catcher and all gathered manually, which is faster than the constant emptying of the basket. The pity is that the finish of the boom has suffered of the box. I'm curious, how long to keep the wheels ... Conclusion: artisans who are skilled and repair or sometimes can paint something have here an instrument with which they can live. There is no special wheel bolts and possibly irreparably breaking plastic - for peeling paint. Someone with two left hands is discouraged by this unit.
