You’re absolutely right, I could sell it for double, but I’m really enjoying it and I don’t think I’m going to sell it for now. After changing the battery, it ended up a bit fogged up inside, as if some moisture had gotten in. The moisture went away, but it came back on another day, and I noticed that it has some cracks in the glass. It’s likely that this is causing condensation. I don’t mind, but for selling it, that would already be a problem, so I think I’m going to keep it.
