I purchased this device months ago, can no longer find it for sale. Doing a search, found this:
https://www.alibaba.com/product-detail/Electronic-Enema-Kit-with-Camera-6_1600368200465.html
It charges via a usb port. It holds 4.5 ounces of liquid. It came with a qr code with the url for the software, lost the code and have been unable to find the android app. When the button/s are held down, a wifi hotspot is created. One would go to the url and the web-base software would show what the camera sees. If one presses another button, it pumps water. There are four nozzles. The very end of the device is the camera lens.
I have another device sold as an ear endoscope. The software looks the same but this version only looks for the small endoscope, not the enema camera. For giggles just filled it with water and gave myself a squirt. 4 ounces of water does very little. I'd try something else but don't want to damage the pump.
Getting back to this thread, my guess the one advertised by amazon doesn't hold much water either, but worth a try. In my opinion, a waste of money, but who knows, you might like it. - the hoseman1
Caution, this site is full of pop-ups.
I bought this on ebay from "musicome." It was under $30, says no longer available.
