I was almost ready to look for alternatives to using the concentrated Castile soaps I buy because it seemed I could not get the benefits I was looking for, wasn't sure how to mix them correctly and at what ratio, and they are not cheap so I do not like to be wasteful. Even if you use regular soaps that are not concentrated, this is great, four parts water, one part soap and voila!! This will pay for itself the first month no doubt. I will definitely get one for kitchen as well, I have this one in the shower area. And most likely will get another one to have near the sink. Easy to take off to fill, and a little soap makes a lot of foam, makes washing a breeze. You can leave it on the handy stand it comes with (for the option to hang it up) as you charge it with the USB cord, or if you need to get closer to an outlet it screws off smoothly. Just unbelievably pleased to have come across this, great investment and the price is amazing! Excellent gift idea as well, especially for those who care about ecology! They will think you spent a fortune, but in the mix of it you will have saved just that!
