I dont understand you guys, IR means inferred which means that remote and device need to have clear view of each other. RF is radio frequency which means remote and device do Not need a clear line of sight meaning it can bounce off of objects to reach device

The issue is that most dedicated IR remotes (i.e. the ones that come with TVs, etc.) have a pretty wide emission angle. The one in the G3 is pretty narrow. It is also probably very low power compared to dedicated remotes. So, its performance is lacking.
