Second time I slipped on the early morning grass wet with dew and broke my ankle. I got used to it. But these are heavier than those and looser fitting. They just dont do what they claim to do. Because the lens of the camera has to be pretty small to fit in your ear, dont expect stellar, hi-def image qualify, but I could clearly see my ear drum. I highly recommend these to people working around water and slippery surfaces. 2 ENORME To put it bluntly, since I was NOT using this on a desktop and therefore could not use the template, I can concur with some other reviewers; It does NOT spread well (I wound up throwing caution to the wind, using a plastic knife edge to simply blot it down, and then spread it evenly as best I could). I will be purchasing another. 3 and v4, and older simulators.
