I've been with Dish 18 years, here's my loyalty reward: Hopper #2 has hard disk failure, fortunately it's intermittent and I was able to back up the receiver settings and copy off the recordings. Replacement hopper #3 arrives in mail, so I set it up. I call to activate it and I'm told they sent the replacement for Hopper #1. What? Bottom line, through Dish's lousy attention to detail and inflexible accounting system if I send back Hopper #2, in a month or so Dish will charge me for not returning Hopper #1. A very apologetic and nice-guy CSR said "you don't want that hassle". Solution? Hopper #4 is in the mail and I have to return both Hopper #1 and #2. I can rearrange my 600+ recordings on my own. Thanks again Dish, you've made my day.
Moral of the story: If you have more than one receiver, make them verify which one they are replacing. And get the CSR's name & number.
