JBL Cascade? Kind of a waste of money, in my opinion.
Here’s exactly how these things work.
You got a closed rubber bag, filled with water.
The material is thick, about like a standard red rubber enema bag.
There is a short little nozzle attached to the side of the bag.
You fill the device, and guide the nozzle into your rectum, as you sit down and put all of your weight on the rubber bag filled with liquid.
Imagine sitting on a little throw pillow, like a couch has.
Next, you open a valve, that extends out, between your legs.
That allows the water to release, and then the weight of you sitting on the bag drives the water up, through the little nozzle, and into your rectum.
With all of your weight on this rubber bag, the water will come squirting out fast.
You have to stay seated on it, until all of the water is pushed up, out of the bag, and into your body.
If you wanted to turn it on and off, you’d have to reach down, between your legs, and play with the valve.
At $10, or $20, sure, go for it.
But, at the prices they charge for them, I think not!
