Should you get an Ultrasonic Cleaner for Bike Parts?

Testing the 10L Vevor ultrasonic cleaner on bikes parts both new and old. See how well it works and if you actually need one.

Those cassettes are that colour from new.

That makes a lot of sense, my only experience with cassettes are contemporary ones that were pure silver when new, older ones must be different. thanks!
