KoolYourPool Pool Aerators

I have these, which look to be very similar and am happy with the results. For $100 I can knock off 2-4 degrees.

I bought one from pinch a penny that didn't have as fine of a mist but half the price that I returned. Its annoying to spend $100 on something that likely costs under $5 to manufacture, but then I jump in the pool and figure it was $ well spent.

I have one of these & it works just fine for $17 - i can’t see paying $100+ for one.
