Concerned about the quality of the internals of this device but externally it looks and performs like the OEM. Time will tell if it lasts as long.

Very impressed with unit although the two pin (USA) adaptor didn't quite fit like the OEM - but I changed it out for the original and it was a perfect replica (minus the logo on the body). The unit - after the first 20 hours, looks and performs just like the OEM unit - delighted with it. The packaging and the service were fantastic...its a shame that Canada Post didn't deliver as efficiently, missing their own emailed delivery date by three days...just from BC to Edmonton AB !!!! Doh !

Good substitute to the overpriced product from the original manufacturer. Using it for a few months now, no problems.

Hate the charger itself. It is a really bad design on apple's part. But I like that the seller delivered it quickly and without issue. It works as advertised.

Works great! No need to spend $100 at Apple Store unkess you're looking for "brand name." My MacBook don't know the difference.

Great replacement part -- I needed a replacement as the cable connecting to the adapter started to fray. So I tossed that part, purchased this one, and attached the extension I already had. Definitely recommend it. It does get hot, but not hotter than the original apple part.
