We've had it since the early 90's back when you had to buy your own equipment. Whenever we had a problem they took care of it right away, only time we have to wait for anything is when a receiver goes bad, with electronics that is expected takes a couple days to get a new one.
Great picture with the new TV's. Add more receivers for $5 more per month, wish Sirus was like that, You will lose signal when a bad storm hits, snow or rain. It usually only last a short time. Seems to be worst on HD but you can switch to non HD channel as they give you both for most channels if you get HD. I mounted my own antenna as I didn't want them to put holes in my roof, I mounted it on the fascia where it was solid I think they will also mount on a pole not sure if that is extra. Outside of bills going up no complaints, but then what bill doesn't go up.
My dish doesn't seem to be effected by snow or Ice but I have cleared if off once and have had ice and snow on it. Good thing about it is a storm comes through and take out electric poles or cable lines you don't have to wait for them to repair the line. Last time we lost electric poles for a week or two we just fired up the generator and were back in service as soon as we started the generator, while the cable people didn't get service for almost a month.
