Anyone ever used WordsTheir Way?

I’m wondering if this would be a good fit for a dyslexic kiddos for spelling. It’s not Orton-Gillingham I know, but it seems simple to add onto what we do already. Anyone have experience with this program?

Here’s a link https://www.rainbowresource.com/prodlist.php?subject=Phonics/5&category=Words+Their+Way+2005+Ed./6671

I have looked at that program too! We have not used it, but I am interested to see what someone that has used it says.
