Very disappointed with niimbot. Since I bought the B101, I've never been able to sign up for the app's vip plan, to have full access without restrictions, it always gives me an error. I contacted them by email and they simply told me to wait and never got back to me. They could have cared more about my situation, generated an external charge, or even a courtesy, if they really cared about the customer who opted for their brand. After all, it's your app's mistake, not mine. In short, disappointed.
