My power cable rubber is splitting apart

I treat them very carefully. I do have to carry the Macbook to my practice rooms every day, so the cable gets wound up in a large circle, like you would with any cable, twice a day. This in not unusual practice and what a laptop is intended for. PC's don't have this problem they are made of a nice strong plastic. It appears that the cable housing on Macs are a soft rubber (really soft you can push through with a fingernail if you try). This is not what normal cables are made of, those on PC's as well as any other electric cable.

Its very aesthetic, but its rubbish long term. They don't last. I look after my electronics. I have the best Thule carry bags to make sure they don't get damaged and my Macbook is in perfect nick. I even have an iSkin on my keyboard, because once again the keboard is matt, very aesthetic, but after using it for a few months the keys start to shine, making it look old and used.

Just brushing my complaint off because your cables are fine is not a good response. Do you carry yours around twice a day and how do you wrap the cable when you put it in a bag? In fact come to think of it I have seen other Mac users cables with the same problem.

No Csound1 it was not an assumption, it was a question. I asked you, "Do you carry yours around twice a day and how do you wrap the cable when you put it in a bag?" and you have not answered my question, so we still do not know. Do you wrap the cable twice a day, almost every day, for two years? And let me point out that this is not heavy use, it is what laptops are intended for. I had work PC laptops, when I was consulting and I noticed the difference in the quality of the plastic that is used. It doesn't make sense using this soft rubber on something that is intended to be moved about. And as Roger has pointed out I am not an isolated case with "special" issue cables. Sarcasm is the lowest form of wit. You're not as smart as you would like to have people think.

Yes and that's exactly what I haven't been doing. I learned my lesson the first two times and so I have been wrapping it in large circles so there is not so much force at the joins and despite that it has finally torn. It just doesn't make sense using soft rubber. The only sense I can make of it is that it is intended, so that Apple can make more money off of people having to buy new chargers. Replacing an entire charger, and there is nothing wrong with the adapter! Evil genius! I actually remember a colleague, a few years back, having to do the same.

If you compare the plastic that Apple uses on its cables to any other electric cable it is much softer. You could literally cut through it with a fingernail if you wanted to. I have been overly careful when wrapping the charger. I wasted money on two previous chargers, as well as iPhone chargers, and wanted to avoid that this time around. Despite that the cable has split. This is ludicrous! I have a 10 year old extension cable at home that has been put to hard use. Its dirty but not a split anywhere. Its made of hard wearing plastic, the kind that all electric cables are. Cables are not supposed to split, and you shouldn't have to be overly careful with them. You said...

"Correct, wrapping the cable tightly will cause a near right angle at the connection point to the supply. Tightly wrapping cables (especially around those 2 legs) will through repetition fatigue the cable.

That is nonsense, cables are not supposed to do that. You can wrap a PC cable or any other electric cable as tight as you want, they are made to last. One shouldn't have to be as careful as I have been with this last charger cable, and it hasn't even lasted two years. And wrapping the cable around the "legs" on the adapter will fatigue the cable! Isn't that what those two legs are meant for? So using the product as intended will cause it to break. Makes a lot of sense... This may not be a case of deliberate safety violation on the part of Apple, it may be a case of poor endurance testing, and since I am not the only one that this has happened to, failing to listen to consumer feedback and making relevant product adaptations. However I find this unlikely. What are the chances Apple don't know that these cables fail? Draw your own conclusions...
