If you are a huge Cosmere fan and $100/book isn't a big deal then sure. They are cool editions, the artwork is nice, and the extra text/introductions are fun to read.
However, if you are more of a fine book collector and perhaps a casual Sanderson fan, be aware; they are bonded leather(which can be as little as 10-20% real leather) and as a result the covers are hard and not particularly luxurious, the embossing (especially on Elantris) is very very shallow and flakes off easily, the ribbon frays at the bottom and I ended up having to cut off the end and seal with a lighter, the binding, (though I believe it is Smyth sewn) is extremely tight so the books don't lay flat easily.
Just be aware, if you have $10k in Easton Press and Folio Society books on your shelf, the quality here is not up to that standard. Even the standard of $100 EP and FS books, let alone the pricier ones.
That being said, I bought and enjoyed them and will continue to do so.
