My iPod Classic just stopped working one day. I thought maybe it was the battery but it was making this funky clicking noise when plugged in to charge. I used the Yelp feature to get a quote from Arizona iPad Repair (the app prompts you to get quotes from similar businesses so I had the opportunity to comparison shop and preview customer service), The representative asked good questions (that others didn't) and gave me the most competitive quote.
They were able to revive my ipod with some new parts, which are guaranteed! They honored their quote AND had a Yelp deal.
I would totally recommend these folks -- in fact, I already have!
