I have seen a few disparaging comments about the jobo, and their software.
I have the QStarz q1000-p
It lasts around 32 hours on a full charge. I have just used it to record 24x7 for a cruise for 1 week, and a holiday for 1 week. The software included is usable, but the free software bt747 works better, and has much better control over the devices, including, if important to you, recording at 5Hz. With dgps turned on accuracy is great, I can see which side of a motorway I was driving down. I am confident with computers, and I set mine up to automatically detect when the device was in bluetooth range, download and automatically reset the device. I have left the device on whilst in a bag in an airplane before, and gotten tracks of the flight.
