I can basically even plug my speakers: the viewfinder does what it claims to do. However, I find the price in view of the fact that he is really designed very simply, clearly excessive. He definitely worth the effort for photographers who take pictures with the Ricoh mainly in bright Taglicht, or extreme backlight, for all others are in my view not the cost in relation to the benefits. The "best" time of the day, morning and evening, I can even use in backlight the display wonderful and the viewfinder is no advantage. It also eliminates Although the "flying blind" in bright light, but occurs to another flying blind, namely, the "what-makes-you-probably-just -scharf" -Blindflug. In the viewfinder, no information is logically displayed, such as on the selected focus point. Furthermore you should be aware. For glasses of income seekers is indeed not optimal, because the finder frame is at some distance (the inevitably created by the glasses) to recognize only partially. Only if you have the eye very close to the viewfinder, you can see him completely.
