I can tell you from personal experience with softeners like the one you bought (single-vessel, brands like Watts, GE, Kenmore) -- they are mostly junk. The price you paid - it's that inexpensive for a reason.
Problems I've seen with those: poor electronics, not customizable, no battery backup in case of power outage, clogged nozzles/venturi, difficult to service
If you really want a high quality unit, go with valves made by Fleck or Clack. You can find online vendors who sell a kit with all components, so that you can assemble the softener yourself (not difficult at all, minimal tools).
