The Traeger Pro 575 heats up super quick and stays at a constant temp. I ran an 18 hour brisket smoke for its maiden voyage. Normally an 18 hour smoke will consume the weekend, but not this time. The Traeger App ties in seamlessly and I am able to monitor temps  regardless of where I am. It has alarms to notify you if temps exceed your desired range. Traeger really killed it with this one.
