I have used the Sewer Solution for nearly 20 years with excellent results. it's fast, easy, small to store and very clean.
One caution, though, is that while it is a macerator, it's a water jet pump powered unit as opposed to an electrical pump device. The difference is that the SS will use water to pump and this is added to the flow of sewage while the electrical pump does not add any water.
For some sewer systems, the added water is a good thing, for others, maybe not so good.
My only data point came from a maintenance guy at a park several years ago, a modern place on a septic system. he said the added water was a good thing and not to worry about it. YMMV
