Bests & Worsts Reviews from Amazon

I purchased this refurbished product four months ago. The warranty is for three months. The iPad worked well for 3.5 months and then started randomly powering down. I would start working on it and after anywhere from 10 minutes to 30 minutes it shuts down and then powers back up. There is no warning when this will happen. I contacted the seller through Amazon and they said that the product was out of warranty. I would stay away from this seller because the refurbished product did not hold up and the seller would not fix the problem.
