Yes, as Customer Service mentioned in other post, this clock is designed to ring only three times every hour, regardless of the actual time. It will always ring three times, so that’s completely normal. No worries at all!
It doesn’t look like it. Maybe I caught it while visiting my grandmother in the hospital… Mine is an ugly cough that’s been going around for a while. I’ve had it for many days now, and at night it keeps getting worse, and now my stomach is a bit off too. I always say I tend to catch everything, but it doesn’t have to be literally everything
