It's possible you may be able to change your equipment within 30 days. You should contact DIRT and see what they say. I have always told my customers to make sure you know what you want right away because any equipment changes you want to make later will cost money and require signing a new contract. Any upgrade in equipment is suppose to require an install and renewal of contract unless you purchase and install it yourself.
If they didn't have this rule then people would be swapping out equipment all the time and Dish would lose a lot of money.
I definitely agree with your comments. Unfortunately coming from 2 HWS/2 JOEY setup, I really had no way of knowing that the JOEY 2.0 would be so slow. My family was used to their own HWS speed and now with just a JOEY 2, you can definitely feel/see the lag. So I am assuming that a JOEY 4K would ease their pain.
BTW, what is the easiest way to contact DIRT on here?
