I'm not personally familiar with them and there's no hits on a Search thru PF.
Answering your last question first. Breeders do sometimes import from other countries. This is the first time I've heard of poodles coming from South Africa but there's no reason that they shouldn't

. The reason they're importing is more important than
that they're importing.
Usually a breeder will import to bring genetic diversity or to add something to their lines that isn't available elsewhere. Enrapture states that they're breeding for conformation and seem to be breeding for color. I see nothing mentioned about health testing, any showing of their own to continue proving the conformation, and I'm disappointed to see the phrase Tiny Toy. That's simply descriptive of undersize toys which are often subject to even more health issues than an insize toy.
The statement of 20 generations of red is something that someone with more breeding knowledge than I have will need t weigh in on. I'm familiar with some of the other kennels they mention as part of their lines and they're considered good lines so far as I know.
Their website is more what I think of as a placeholder rather than a truly informational site. If I were looking for myself, I wouldn't rule them out automatically but I'd have many questions for them, some of which are in the resources in your other thread.
