Darren was a customer of SmileDirectClub.com, which he considers mail-order teeth straightening. But he did not have a good experience. He was originally inspired by his friend Keith McPherson to join Smile Direct Club, but Keith has had his own frustrations. Jen’s sister Melissa also had a bad experience with Invisalign (their parent company invested into Smile Direct Club), but for different reasons. Both Keith and Melissa join Darren and Jen in the Tech Asylum, to talk about their experiences.
