I've got one - not made by All-Clad - that I bought 20-25 years ago because for some reason I thought I needed it - paid about $10. I have used it to steam other things more than asparagus, like broccoli, cauliflower and small new potatoes - but probably only used it less than a dozen times. Today I use it to hold wooden spoons ....
I find a cheap little fold-out steamer basket much easier, more convenient, and a heck of a lot cheaper to use.
Now, having said all of that - I do understand the "concept" of the asparagus steamer. The stems are tough and if you don't cut or peel them, then the steamer is supposed to make the bottom of the stems cook faster than the tips (since that is where the greatest concentration of heat is supposed to be). And, maybe for asparagus, it might work that way.
Another thing ... it's just a tall thin pot, with a basket insert, to simmer water in. No magical Tri-Ply gonna make it cook better voodo ... read the description ... "the new All-Clad Stainless Asparagus Pot is crafted from high-quality 18/10 stainless steel, and features a thick stainless/aluminum disk at the bottom for the best heat distribution." And, you don't even need that much technology since all you are doing is simmering water!
