My DIL has the Dyson Air Wrap (or something close to that). She has long, naturally wavy, but somewhat unruly hair. She LOVEs her Dyson. She got hers at a Dyson store that existed at least for the holiday season. I’ve seen pretty good deals on them at Ulta. Sometimes they offer promotions and you get extra accessories or whatever. She got hers where she did because they had a better overall package.
ETA if you’re a Costco member, they have it on special for $140 off right now.
