I will echo what Vixtor says about the i3. I have not used one but everyone I know who has used them loves the lever for deflating. No more trying to locate rear dumps or angling your shoulder to vent from the inflator. For inflating I do not see it being any advantage over a regular hose inflator but for deflating from all ports at once has got to be nice.
