I have 2, a queen I got probably 10/12 years ago, love it, you can get ones meant for more mild winters or heavier winters. I got a king one when I lived in CA back in 2019 and had a king size bed. I love them both, and now being in MI they’re usually both on my bed in the winter. They definitely last, and I had one when I was much younger and the down migrated, but a lot of the newer ones(including both of mine) have stitching to prevent that or help reduce it.
