The AC charger for my iPhone went kaput and I found out online that this is a common occurrence. I went to my phone service provider and he told me that the Apple Store will swap out the charger for free.
Arriving, we found the store quite busy so I began to walk to the back of the store to what appeared to be the service desk. On my way there I was very courteously greeted by one of the clerks. I informed him about my situation and he said it was no problem and promptly took care of me. I asked him "if the charger went kaput again can I bring it back"...of course he assured me that it is a very rare occurrence and he stood behind the product. I ask the question again and he finally said "yes" and again reassured me of the product quality. I left with a new AC charger and power cord free of charge.
After reading previous review of bad customer service I was apprehensive of my visit, but this was the only Apple Store within my vicinity. I left a very satisfied customer on this visit.
PS: 4 stars because he dropped it on the floor, hence my asking if I could return it...if it didn't work *L* He had a great sense of humor!
