This was sent to me to use & review, but after much consideration - and having been in the
Plumbing Supply Business for over 40 years - I just did not feel comfortable using such a product.
So many people focus on it's actual performance, & any associated problems, seats not sitting properly, won't fit a round front toilet - only elongated etc.. How they were saving toilet paper and such. But here are my thoughts on it.
First, I don't know what your bathroom is like, but when it's hot in the summer or the heat is on in the winter, my toilet gets those little black mildew spots all under the rim of the bowl & the bottom of the seat. I have to constantly lift the seat & scrub with my toilet brush & flush several times to get them to wash away. So do you think this bidet will NOT be subject to that mildew? My other concern & I'm just going to say it - diarrhea - which sometimes also manages to splash all over the underside of the seat, and the back, inside of the bowl, exactly where this bidet nozzle sits. So my main concern is just how sanitary is this??
The whole idea of using less toilet paper - just what exactly then are you using to dry yourself off with afterwards? Not drying off at all? that will get you "swamp butt". One guy says how he follows up his bidet washing with a cheap bunch of wash cloths he got off Amazon, why not just wash off with a washcloth to begin with then?? With nice WARM water from the sink? :) That is my last concern - I wouldn't be wild about having COLD water splashed at my private lady parts. At least for that concern there is a warm water model also available.
So you will have to decide if this item is for you or not. I'm just putting my thoughts out there.
But I would say easy to clean, more sanitary & warm water is the reason a REAL BIDET is a separate bathroom fixture, with a hot & cold water faucet. Europeans using them for decades, can't be wrong. P.S. And I have to say I don't know what the difference is between the 120 & the 180
