But, the front of the receiver says "Hopper 3 with Sling".Well, Hopper 3, like the label says.
The reason the Hopper 2 was named Hopper w/Sling is that the original Hopper (Hopper 2000) didn't have sling technology.
When the Hopper 3 came out, also with Sling technology, they renamed the previous Hopper 2 and didn't add the "with Sling" to the name of the Hopper 3
