I disagree. I called them and they said that they were very sorry that they could no longer repair my ULD-15 made in 1986, because they no longer have the parts for it. (I don't think that is surprising, since the unit is 20 years old.) They were supportive and offered the name of a company that might be able to repair my unit. They also offered to replace my 20 year-old unit with their current top-line unit AT 75% OFF OF THE LIST PRICE. How much more helpful could they be?
You can't expect them to continue to make and stock parts beyond 20 years, and short of offering me a new sub for free, what more could they do.
I'm happy with the support they offer and I will continue to buy and recommend their products. (which are among the finest subs in the world)
Just my opinion.
