With its push squonk button, the Delta out performs all current squonk mods. In addition, its bottom no mess filling mechanism makes it the most user friendly mod I have used. The coloured visual display and software are excellent, especially when a digital clock is included. Aesthetically brilliant, it feels solid, well made and long lasting. Battery life is very good with the 21700. For me, the Delta has no cons. Cannot recommend it highly enough.
I have a lot of squonk mods, and this is probably the best, easiest to use, dryest, least messy squonk mod I've ever had.
A definite Must Have ... 11/10
