Query: Chinese workmanship on the poor side

THIS IS NOT AN APPLE product, it may be cheap but there is a reason for that. Do yourself a favor, spend a few extra bucks and get the real deal. When I ordered, they had a photo of an Apple power supply as the main image, misleading. I requested and received a refund; they have changed the picture. Tried these units before and nearly caught my house on fire the unit got very hot and actually started smoking.
