Should I invest in one or forget it?

No.
I do know that many women enjoy them.
I personally don't categorize pumps (both clit & penis) as sex toys, although they serve similar purposes. I've just always associated pumps with difficulties becoming aroused, because they're both used that way.
I understand how they are, by nature, erotic. But I don't find them erotic.
I've never tried one, so I'm not trying to deter you. As I've said, many people enjoy them. So if you're into the idea, why not?
