Properly processed, more frequent exchange of consumables required

With the general processing and general use, I was quite happy for a mid-range device. The latex Rope principle stood in my device but as a weak point out: I use it to condition obtaining in the lower area. The first rope held approximately 45,000 strokes, the next three then each between about 15,000 to 25,000 strokes; at 500 beats per exercise a too short time. Within the guarantee the free subsequent delivery of replacement rope was very quick and without any problems. An exchange of the rope is - with a few simple tricks - to do completely within 15 minutes. Meanwhile the device is but from the guarantee: a spare cable costs - excluding shipping - about EUR 8.90. The rope is - no matter what level of resistance - by the (good and smooth-running) pulleys, guide rollers and the rope stretching apparently tumbled, the surface thereby apparently mechanically roughened, dissolved, eventually sticky and tears finally - judging fracture pattern after - due to notch rupture. Since this is done during the notation for a strike, the impact of the broken rope end (25cm) on the rib cage is not entirely painless. That reminds me retrofitting now is cumbersome and too costly in the long run, I now separate myself from this unit.
