I have a Solo 2 currently and like it. I'm tempted to get the camera. Having used it, would you still buy it over a GoPro or other?
Absolutely. I'm not sure what the procedure is now but it used to be a royal pain overlaying data and syncing it with the video. I'm basically lazy and the camera does this for you in conjunction with the Solo 2. Being able to see rpm, gear, speed, throttle position and brake pressure where ever you are on the track tells you at a glance where you are screwing up. The Go Pro shoots higher resolution but that's not why I review video.
Too much of anything is bad,
but too much good whiskey is barely enough.
