I've used the standard version for 3 years, the wide version too for 2 years, and now there's a HD version.
Good thing I read about the latest version, is you can now have a remote control to start it.
I have almost never succeeded in having both cams working at the same time (there's always one which turns itself off before the end of a lap, or I think I started it but didn't). Last time I went to a racetrack, in 5 different sessions, I only have 3 laps in a row with both front and rear cam working.
It's pretty awkward to turn them on and start recording once you have your helmet on, gloves, sunglasses and the sun is shining.
That being said, they're small, the suction cup system is great and you can put them almost anywhere you want (on the roof facing forward, backward, on the windshield, on a fender, I've even used one on the bottom fender 4 inches from the ground, to shoot backwards and see the camber in turns).
There are also several stick-on mounts, but you have to jam something in to avoid vibrations (I used matchsticks).
The settings are fairly simple. From memory, you can set :
- cam position : upside or upside down
- Video : PAL or NTSC, 50 or 60 Hz
- Mic gain, Low or High (use low for motorsports)
Yes, they are waterproof.
Only best thing is a separate cam and a digital recorder inside the car, but that's a lot pricier. It's also a lot better if you can use a 2- or 4-way recorder with several cams.
Some suppliers now offer motorsport-specific items, with data acquisition systems, which can automatically blend video with inset information from the acquired data (think video with speed, rpms, skidpad info and the like). Pricey too...
There are also a couple similarly-priced alternatives, with similar features.
Some have playback capabilities :
