I'm on my third set of E-Flex and despite not initially liking them, I've completely changed my opinion after a couple of minor mods.
First thing I disliked was the tendency of the ears to rotate upwards slightly, even with the clips in place, leaving a small gap between ears and faceplate. Not enough to be hazardous, just unsightly and annoying. Took a leaf out of the i4 book and glued velcro on the lower corners of the ears and inside the faceplate - keeps the ears tight up against the faceplate at all times.
Second issue was lack of forehead protection - solved with E-Vents visor. Wish they'd include one with the E-Flex!
Final issue was the way the mask sat on my nose - it always felt as if it was putting a lot of pressure on the bridge and never felt comfy. Recently double strapped them and it's a revelation! With stock strap behind my head and the second strap located higher up it seems to completely eliminate pressure on my nose and makes them feel very secure on my face. Absolutely love them now. My i4s and Grills don't get a look in!
