Got a set of them on my Monarch II. What sold me was I went to change the oil after a trip out west and found a big chunk over an inch around and over a 1/16 deep missing from the front of one of the aquashields. Whatever smacked it probably wouldve taken out the Missus leg. Right there they earned their keep in my eyes. I have an aquaintance who has a 1500 with no shields and his wife complains especially in construction zones about dust and debris blowing on her lower legs. To me its a personal choice but it really finishes off the look of the trike at least in my eyes.
