They may deteriorate over time, I don't know. I bought my 20 degree Slickbag used off a forum probably around 6 years ago now and it still works well. I store it draped over a rail in a closet so it's not compressed. I think they have improved the insulation since then, but I can't complain about mine. With merino and fleece layers I've used it down to 0 degrees in Wyoming with no complaints. Last year in Alaska it rained for 5 days almost constantly and I used it to dry gear in our tipi. I've had it against the condensated wall of the tipi to many times also and never got wet inside it. I know down has it's place but my Kifaru bag has worked so well I haven't talked myself into trying anything else.
