The "little pen" was never put in the slot. Even if I did my best to push it down, if I suffered the second twist with the stylus as far down as possible, everything would happen that the numbers on the dial would start moving. This applied to both castles. At this point, even if I could get them to work, I wouldn't because I couldn't believe they were buggy and I would have to turn them off. As for the cost, it's not worth my time and effort to return them so they end up in the trash. Measured by the percentage of similar reviews, the probability of production failure is about 7-8%. it's pretty pathetic.
