I like that River Cleaner has more than one type of cleanse, so I can pick the one that best fits my skin. It also allows me to skip over ingredients that don't feel good. I dislike having to wait around for the machine to do its work. I wish I could just turn it off and on myself when I wanted. As with other machine cleansers, I prefer the feeling of a warm or hot washcloth on my skin. It is very easy for me to understand which products are performing well and which are not, or need more reviews etc. I didn't find any downsides so far as this software is doing all that it claims to do. The interface could look better but it doesn't really matter much since it's not used everyday. I highly recommend this tool for anyone in eCommerce business. It makes life easier by providing insights into what items are performing well and which ones aren't.
