Hi Debbie,
Yes, they did, but evidently, they got so much flack from customers, they decided to do a last run of 4,000 Sirens. They're also testing a v2 Siren now, but that's supposed to be a secret. No info on the release date of the v2. I'm happy they're coming out with a v2, but I'd love it even more if they'd keep the v1 on the market too, with minor fixes like a smaller air hole, tightening the pin and installing a seal at the bottom of the airflow tube.
If you want a V1, they are available at Myvpro.com, Eciggity, 3AVAPE.com & Efun.top. They may be available at other outlets as well, but these are the only ones I can think of right now.
