Emsculpt Neo - how frequently should maintenance treatments be?

Hi, I am considering Emsculpt Neo but I have some questions about the number of treatments as I have received conflicting information from the clinic that I have had a consultation with. They advise having 4sessions, one a week, which is what seems to be quite standard practice. When I asked about maintenance treatments, they suggested that I should have another four treatments 2 months later. This seems like a lot. Is this necessary? I want to see great results but this would be costly!
