I couldn't live with the Sapphire alone either , but its worth having on the van , its a joy to use when when the job is suitable . But its not so good on curved areas ,sharp angles ,crevices , buttons , piping , etc and if its really dirty iv found it even after good preparation it would take about 10 passes to equal one or two on my other main tool , a metal enclosed spray out tool , never had a CFR would like to try one though .
