Jebao sow8 question- blades never stop

[Elmareefer]

I have 2 jebao sow8 wave makers I just purchased

In modes W1. W2 the blades never actually stop
Is this correct? I saw an older video 8 years old where the blades do stop in those modes to produce waves

Anyone familiar with?

I have different jebaos but they all have those modes. Pulse yes, stop no, as far as I've witnessed.

Mine slow but don’t stop. Never really thought about it to be honest.
