No complaints and reliable, my EDC for over a year for "when-you-need-a-light" situations. Brightness is more than enought IMO for most tasks, such as navigating in a dark movie house or looking thru corners. First bought the white but changed it to red for night-adaptation. Size-wise, I prefer them over the Photons' as the Photonlights were too tiny for me.
My only gripe, if anyone from INOVA is looking, would be the clip. For me, it needs to be more secure as it could--and did--unhook one time (taped the ends with duck tape) and it it could also turn/twist/pivot to give it more direction during lighting tasks.
