I had expected much more from Garmin. Though this is the 1st generator Virb, there are enough camera's out there to get an idea of what users would desire. The design is great, it addressed many issues a cyclist would want in a camera, such as a top mounted LCS display (the GoPro has a forward mounted display, which is useless if you want to watch battery life etc). However the issues begin once the unit is turned ON. There is a lag between input and output of video, this can cause the display to glitch at times. The unit also freezes up at times. Once you get to know the quirks, you can get around them, but many times it requires a restart. The dashboard is a disappointment, as I'd have hoped to choose what I wanted displayed on the screen and to be able to choose where that location would be... as the display fields are on the Edge. I realize that power sensors wasn't one of the types of data this unit would pick up, but seriously, I'd put up with a lot from this unit, if it had the ability to sense my power meter. But given the issues I've had, and amount of hair I've lost in frustration, I will be sending my unit back. Maybe by the second or third generation they will have improved the software and processor speed to meet demanding expectations. I'll stick with my GoPro3+ until then... I had really hoped this would have been a good replacement, but alas this unit has far to go before I try testing out another Garmin camera.
