If you are looking for some cheap ergonomic hooks go to Joann’s! They are 40% off! There weren’t to many sizes though, they had 4.25 4.5 and 5.25 at my store.
Ok this is an update: the hook is difficult to use it splits yarn it squeaks when you crochet it is a little bit rough at the edge of the hook so it catches yarn and frays it a little I don’t have any Boye hooks though so it could just be because I have never used boye before
Update 2: the hook is getting easier to use the more I crochet! I think the acrylic fibers smoothed out the rough edge so my stitches are gliding easier.
