Easy to assemble, easy installation, good quality, looks good, good evaluation. Safety acc. Test results pirma (must be hopefully never tried) Only the belt guide on the head part is very ill-conceived. Belt slips like from said guide and then rolls not decent on. (Please "Romans" abschauen, can not be that hard, and is in the Prod. Also not expensive) Yes, why -1 star. Trotdem worth a recommendation.
