Does the 50Hz & 60Hz difference matter at all or not? (feddit.online)

The 240-120 voltage problem can be remedied by using transformers but that doesn't negate the frequency difference between grids. Australia operates on 230v @ 50Hz while the US works with 120V @ 60Hz for instance, as certain electronics that are singular voltage (Hair Dryers, Desk Fans or Electric Blankets) have their frequencies disclosed even if the voltage on those are different than the one that country uses.

Does plugging in a device that has 120v-60Hz via a transformer on a grid that operates on 230v-50Hz ruin the device due to either heating elements or motors inside? Even between countries that work with 220-40v but one uses 50Hz while the other uses 60Hz, does that render those electronics (like dehumidifiers, power drills, curling irons) incompatible despite them using similar voltage (like 220v vs 230v)?

It helps a lot that appliances for the Japanese domestic were designed to cope with different frequencies (for better or worse) from day one, as it's cheaper than having two almost identical product ranges. Motor and transformer windings designed to tolerate the extra current when running @ 50Hz, or switchable winding taps if efficiency mattered. Different pulleys / switchable gears for things where speed matters, like record players and electro-mechanical clocks.
