There are dozens of other companies out there with the same or better. They also have working products in the field. I posted a handful of them with links but were removed for being off topic. Check India and Africa with a google search, you will find them.
Also on the other side of things, the RO units. There are literally hundreds of them out there with the same or better products. This company sells them through network marketing which almost always means higher prices for the units. This info is also available through a google search.
