Pros: No need to go to the bathroom or kitchen any more
Cons: Didn't work on my french toilet
I bought one of these while travelling, having used it by friends. It was very very useful, and I wanted the same at my home !!!
Unfortunately, I wasn't able to install it on my (french) toilet : mecanisms into the tank were soooo different from the one supposed to be in for dealing with sinkpositive.
So, I had to look for another one in my country : the WiCi Concept product (see http://www.wici-concept.com ) appeared to be more expensive, but I was able to install it on my toilet, and it also provided more functions (automatic faucet, soap dispenser).
