Overall, i am very pleased w this device. The Smart temp feature is really nice. Allows the blooms to be slowly and more enjoyably consumed. And what’s interesting is i realize when the temp actually starts going past 400f, it’s time to reload, as i have a more sat. preference. That said, unfortunately, the app really doesn’t work. Nice idea w all of the features mentioned in the manual, but the Bluetooth attempts have only ended in failure 😂. Also, the battery is ok, but not yet convinced it’s a 1.5hr capacity. Still measuring and getting more familiar w some of the other buttons:lights functions. Anyway, thanks for a decent product.
