Ivape shipped my VariStack promptly and it arrived two days later.
For $40 I wasn't expecting much but was pleasantly surprised.
The VariStack looks and feels so much better than one can interpret from the pictures. The square top part fits the thump and forefinger naturally with thumb comfortably on the fire button. With very little movement the thumb can curl around the edge to comfortably adjust the voltage up or down without readjusting the hand hold on the unit.
Number will continue to scroll up or down as long as the +- button is held down, much more convenient than other VV units I have.
The screen is a large 1/4"H x 9/16"W with easy to read bright red numbers, very nice for those of us who need reading glasses.
The VariStack will not handle LR vaporizers but handles my 2.4ohm Vision Deux well into the 5v range which is way too hot. Same with a 2.2ohm Stardust. No problem going to 6v with anything I have over 2.9ohm such a 2.9ohm 901 atty, a 3.0 ohm IKV Mega Carto and 3.5ohm IKV io6 atty
Any questions? Feel free to ask.
Steve K will be doing a more comprehensive review on the VariStack next week, possibly as early as Tuesday.
