Have not used the prop guards on Enterprise Evo 2, however have flown many flights mainly indoors and some outside with regular Evo 2 and Evo 2 Pro. As prop guards they are good and do what they are intended for (e.g. saving the aircraft and other things) from when you bump into them. Do they provide protection from whats above or below? No, just like other prop guards they are just providing side, front, and rear protection. Otoh, would be nice to have a prop cage that provides top and bottom protection like the prop cage for DJI Mavic Mini.
