I like my Wolfbox mirror (G930) a lot. The image is super clear (during the day), the added functionality of having a dash cam with an included SD card is a nice bonus, my mirror has the GPS feature, so having the direction you're going and your speed displayed on the mirror is nice, and it looks kinda OEM-ish. The mirror is usually the first thing I get comments on when people ride in my LX. The only drawback that I see is that the night time image isn't great. You can see the street lights and headlights of other cars just fine, but it's hard to make out fine detail at night. They do sell a wide dynamic range (WDR) camera that you can buy separately. It's supposed to give a better night time image, so that might be an upgrade purchase in the future.
I ended up buying Wolfbox's license plate kit which mounts the camera on top of your license plate. I like this location as it gives a good image position and you can barely see the camera in this location.
