No no, there is nothing wrong with your Vamo. I have had a similar experience, as have others over in the
Vamo user check in Thread.
I've dropped my Vamo a few times already and although on the face of it it's unscathed, the drops do seem to have an taken their toll. What happened is the board inside moved a little, PepNYC has a solution for this.
I think mine is welded together, nothing will pry it open and I can't get to the board unless I use needle nose pliers, being the clutz I am I know it'll be a Disaster, my impatience got the better of me so I just knocked it on my hand a few times (ok many times) (hard) and tried again, the negative button works better although not as responsive but at least now I don't have to sprain my thumb every time I need to change up or check Ω's.
