I guess it's kind of strange to be enthusiastic about a toilet bowl cleaner, but this stuff is great!
The company that makes it says that their products are much better for the environment than conventional cleaners.
The toilet bowl cleaner has a very pleasant smell that's not too strong. It gets the job done as far as cleaning the bowl. It's also easy to open, which I like because I've had trouble opening the bottles of some of the conventional toilet bowl cleaners (I think it was Lysol, if I'm remembering correctly, that had an especially difficult-to-open bottle).
The cleaner is a bit expensive to buy, but a single bottle lasts for a really long time, so in the end, I think it's a bargain.
And I like feeling that I'm doing a little bit to help keep lakes and rivers free of toxic chemicals.
