This 85W Mac charger works perfectly, and costs a third of the original. I've used it for 2 weeks now and not had any problems. The actual product looks exactly like the original (complete with Apple logo instead of Laprite) so if you're looking for an exact replacement, this one comes very close.

The charger doesn't heat up, charges just as quickly, and most important - the cable seems more robust than the original Apple one.

Bought the charger in Jul'15. Bought it for my office usage. One fine day, the charger went kaput in Feb'15. Unfortunately, there is only 3 month warranty.
