This seems to be a landlord and tenant matter rather than a strata issue? Though I imagine Flatchatters who are investors/landlords would be very interested.
Just over 50 percent of apartment residents are tenants, so around 50 percent of apartment owners are landlords. That makes it relevant, in my book.
Also, I had a look around for the price on a second-hand induction cooktop on Gumtree. One was for sale because it had been cracked by a falling pepper mill. Maybe there should be a warning about storing heavy stuff above them.
