To the customer, and I think many will agree, it's too slow though. This is especially true for anyone who has had cable TV service. The cablecos have offices and now "stores" where you can swap equipment quickly and easily*. I know from my experience (just under two years) with cable DVRs, they gave NO warning when the HDD was going to die. With Dish's DVRs, they tend to act up by acting glitchy with anything related to pausing, rewinding, playback, etc. That alone isn't a guarantee it's going to die either, so you almost have to wait until it gets worse and finally, it spits out an error code confirming the HDD is dead. Then the wait begins... In my experience, you'll be without a working receiver for a minimum of (3) days and up to (5) won't be uncommon. That starts when you call (for me, it's always in the late afternoon or evening), I've never seen "same-day shipping" that I can recall, and unless you pay extra, they ship by UPS Ground. For my location, that's (2) more days. That all said, I personally could care less if I couldn't watch TV for a few days or more. A lot of people can't say that though....
* Back when Dish took over Blockbuster, there was talk of allowing customers to swap receivers through these stores. That was the only good thing I saw from that adventure.
