Yep spinning wheel is culprit. I just want my money back at this point. have had for a week. Would like something w/o pulse modulation like a Provari. MVP looks like a pin with no spare battery option.
MVP2 is nice enough for the $45 I spent (except I "had" to buy three of them, ugh). But yeah, there's the trouble with the finicky connector issue. You do sound like the Provari would serve you very well. I can't say I've ever heard a single true complaint about those (I'm a Reonaut through and through, but I support and appreciate the VV needs of others, lol). Now you just have to find your ideal "juice delivery device."
