    To those that have had problems...

    I've read several of the reviews about this charger. It definitely has issues. It gets hot while it works and will shut down if it's too hot. The cording also has been a problem, but I've had several of these chargers. My earliest one had a cable that frayed at the magnetic end of the cable. The cable just split open, and so I put a piece of heat shrink tubing over it, which held it for awhile. But then, if I used my laptop on the bed, I began to notice light gray flecks of rubber laying around. It was from the magnetic cord that attaches to your laptop, not the AC cord. The earlier cables were made out of a different kind of rubbery plastic. At some point, it will simply disintegrate on its own. Eventually, that power supply's cable lost almost all of its rubber coating on the entire cable, leaving bits and pieces of rubber anywhere I used it, exposing the braided shield. I bought another one and threw the old one away. The newer model's cable wasn't as flexible as the older model. It felt more or less like Teflon. It was a bit stiffer, but it hasn't frayed at all, and while the box itself still gets hot, the cable is holding up well. These power supplies for the most part are fairly reliable, unless you have one of the early models with the different cable composition. And yes, Apple needs to made a charger where the cable can be easily detached and replaced, especially if you travel a lot with your laptop. Also, be careful to not cover the charger box with anything so it can ventilate.

    needs to be better

    As with others comments, I have needed to replace the charger once. The second one will be replaced when I have money to do so. I am happy to read others have had problems with fraying.

    Second charger and still working

    I have a Macbook pro 15" Mid 2012. The first charger that I had with this computer got damaged in a year; the cable broke near the plastic charger.
    The second charger that I bought (from Apple Reatiler in Colombia) is working until now, I think that the most important thing to do is not trying to bend the thin cable under any circumstance, this strategy worked for me, and I pack the charger in my bag without bending this cable.
    Besides of that, I think that Apple engineers must redesign the thin cable on newer models, because it's so fragile.

    Buying yet another due to frayed cord

    As reviews say over and over, cord frays, these don't last, they're expensive for a disposable item.
    Compared to power adapters for other powerful laptops I've had these are exceptionally light and easy to carry, and the mag attachment is awesome. That's why some stars.

    Notice how "most useful" reviews shown are 5-star? How deceptive is that! Its like Apple wants us to hate them.

    Too Short a Life Span

    This charger is relatively small, attractive, and gets the job done. I like the magnetic plug - it has prevented many accidents where my laptop would have been dropped. But I can give it no more than 3 stars because its life span is about 1 year if you're lucky. The end that you plug into the computer is made of a flimsy rubbery plastic material that frays and comes apart after even gentle use. My laptop does very little traveling - it usually just sits at my desk or couch - but after just 9 months I was having to reinforce the adapter with electrical tape so that the wires weren't exposed. This is a huge problem with this power adapter, and I'm surprised that Apple hasn't come out with an improvement yet. I won't be paying 79.00 for Apple's, especially when I know it won't be lasting long anyway.

    New Mag Safe

    It seems a shame it took Apple this long to replace the worthless adapter the originally produced and have not yet taken off the market. They were very prone to breaking and or burning. I replace 4 in a two year stretch.
