How about some thoughts on your best purchase (not limited to enema gear). I described in another post my best purchase and it was even designed for use as an enema.
I used to have a really nice bag that was really for "feminine hygiene" (douche bag). It had a sort of flap type valve at the top that was pressed up against a faucet and the water pressure would expand the rather small bag like a balloon. The bag would remain inflated with water until you inserted the nozzle into the neck of the bag where the flap valve was located. Unfortunately, I usually would abuse the bag by expanding it to well beyond its intended capacity (probably at least two quarts)and I think this caused its demise. I had one explode like a balloon and then another one began leaking at the flap valve. Have been unable to find this bag anywhere, but it was definitely my favorite. Kind of a cross between a bag and a humongous bulb. Many fond memories of using this bag (sigh...)
