Hated Sprint, love Ting. For one, somehow Sprint phones due to cell towers would drop your cell service and you wouldn't know till someone told you that they had tried to call you and couldn't connect. Prices were another issue (random change of how they charge in the middle of a plan, that one got them cancelled).
Ting has only ever done that once (not a hundred times) and their pricing is awesome. Customer service is also remarkably helpful. So yes, I can see rating Sprint horribly and Ting wonderfully because I would too.
