I have the Basic H2 concentrate. I also bought the Shaklee bottles, it's a set of 3, for diluting it out to : a window/mirror cleaner, all purpose cleaner, and a de-greaser. The bottles are pretty, but totally not necessary. I did also buy a couple of their window/mirror microfiber cloths.
The window cleaner is probably my favorite. It is amazing. I use it on all our windows, the TV (fingerprints

), the mirrors. They have never been so clean. I swear it get my front door so clean, you might not even realize that there is a glass (storm door) there.
The all purpose cleaner I just use for counter tops and stuff.
The de-greaser works really well to clean my stove top. (Smooth surface burners)
I have also used a tiny squirt of the concentrate to clean the toilets too. I'm sure it has lots of other uses. But that is how I use it so far.
