NF Tech Services (Operating Trade Name of Ohio company Spring Run Group LLC) is a technology services company with the web address www.nftechservices.com. The company is well known for their service and sale of Apple products, including notebooks, desktops, and the iPod music player. The company is known for its "mail-in" iPod repair, in which the customer fills out a service request and ships their iPod to the company for repair and return. This is a fast-growing industry which is gaining massive market share as warranty coverage of over 100 million iPods, sold by Apple since 2002, lapses. Third party repair services such as the one provided by NF Tech Services are traditionally more popular with consumers due to lower prices than the services provided by Apple. NF Tech Services is also the only major online shop dealing in Apple products to offer a sale service, in which the customer can sell their used Apple product to the company and receive payment without purchasing an item from the store.
