I would not recommend Digital Doc in Chesterfield, MO to anyone. I purchased 3 iPhone 6 foot long heavy duty charging cables from this store and 2 of the 3 are no longer working. When I called the store to ask if I could exchange the cables for another set of working cables I was told they are only guaranteed for 15 days. I paid a premium for the products I bought at this store because I was under the impression that Digital DOC would backup their products but apparently the merchandise sold in this store is no better quality than the cables that are sold at a local gas station. I will never shop at this store ever again and I will be letting all my friends and neighbors know about the horrible service I experienced at this location.
