I do own the Xeno E03 XP-G R5 CW... I had to switch out the clicky in the beginning, because I had flickering problems. They were gone after I switched the clicky with the spare one provided in the package. HKE is cool, they even offered to send an additional spare clicky. The balder seems to sometimes also suffer from bad switches... I will never understand why manufacturers are willingly sending spare clickies instead spending an extra dollar on the installed one to get higher quality. I don't use my E03 as often as I thought I would be... an improvement was adding a Fenix LD-20 clip and that standard Fenix diffusers (same head diameter of 21.5 mm as the LD10 etc) fit it perfectly... so I use mine mainly as clip-on lantern for working on near-field stuff. For traditional flashlight use on NiMHs I mainly grab my Hugsby P31/P32/ Klarus P1A, but they might be too throwy for your taste.
