i have used both the cfr and the drimaster, both excellent tools
i decided on the drimaster, simply because ease of use, no trigger to worry about, no over spray
no need for drying strokes, hence cleaning times cut down.
the one negative side, the filter does need to be cleaned on a very regular basis, a very fine mesh in line filter soon can get blocked , resulting in loss of solution to the head. out comes the spanner to undo , clean filter put back , can get a little annoying . perhaps Hydra master could incorporate some sort of quick release filter system . would be a vast step forward " just a thought"
