I have both and for some reason the dabox isn’t temperamental for me..I have used both types of coils and there is a difference but not sure what it is..lol..at first I loved it but it sits unused on my shelf..I, digging the sequoia which is the bigger sai but I need to download a better firmware to get a more accurate temp control.id go with the sai.
FWIW I tried to talk to
@Vivant by email about my dabox possibly having an issue because at first it rocked at then it got worse like it was losing power but they didn’t wanna hear any of that. Basically in so many words that it was solid product and never hear of my issues..so I gave up
