Reviewing a friend's version of the shower enema, the SirClean. (For the record, he gave me a freebie on the grounds of asking for a review, but I'll try to be fair and unbiased nevertheless.) My background is as a pro-domme.
Basically, the SirClean is your typical shower-attached enema with one major difference: it's got a valve on the nozzle end. So, when you divert to it, water flow stops until you squeeze the trigger. Using it as a toy, this makes a huge difference: I can pause the flow, deliver a little spanking, add a bit more enema, pause a bit and taunt some, deliver a bit more enema... previously I could only do this with a bag. (I suppose I could have inserted and removed the nozzle and just let the water run between fill-ups, but that just seems hokey.) Upside is it's definitely easier than messing around with bags, limitation is it isn't portable (I can't take it to the dungeon and administer it to someone tied up there).
I tried it once with a client on the toilet, but that didn't work well. Can't see the anus to get easy insertion. As a solo thing, though, it looks like it would work.
The nozzle is a stiff metal tube with a little bulb on the end, several inches long, with a curve to it. The water comes out the tip (as opposed to the sides, like the "douche" nozzle that comes with bags.)
Cleaning-wise, it's a metal handle, metal nozzle, cleans up easy. Between uses, since it's being shared between non-bonded people, I take the nozzle part off (it takes two adjustable wrenches) and soak it in glutaraldehyde (a medical-grade sterilant). It's inconvenient, but then so are STDs; this approach is probably overkill for anyone who's not a pro-domme. More a nuisance than hard.
There's a different model, too, with a rubber nozzle. I didn't care for that one... not for enemas, anyway. I could see it as a bidet, but... meh, at least from my standpoint.
The hose has a metal appearance but isn't, by feel maybe flexible PVC. It's not quite as cool appearing as stainless hoses but it's smooth and possibly easier to clean off soap scum and other bathroom crud.
He also markets it as a douche, so after a dip in sterilant I tried this on myself, and it's okay. Not as fun as the pulsating adjustable massaging showerhead, but, y'know, it does its job. Easier a bag, definite better than those useless little Summer's Eve things.
So... I can't think of anything else to say about it. Overall: A nice addition to my equipment. For those interested, you can search it out as SirClean on the 'net. Joyous enemas 😃 !
