Review on XOSS G+ GPS Bike Computer: ANT+ with 2 Smart Cadence Sensor, Bluetooth Connectivity, Wireless Bicycle Speedometer Odometer, Waterproof MTB Tracker for All Bikes (Heart Rate Monitor Support) by Tim Evans

Shipping to New Zealand. Easy to set up (I'm 60). There are cadence and speed sensors. I removed the cadence sensor after a few rides as it only fit on the outside of the crank and got hit, but I also realized that I didn't really need the cadence. The first ride also used my phone with a tracking program. They appeared to be the same in terms of distance/time etc. This device gives me power/avgs and max speed. It displays time and time in chronological order, driving time and total time. It stops counting when I stop driving. The GPS makes a good connection - maybe you just need to get outdoors a bit. Mine seems to connect quickly when I actually start. There were some problems at first, but it was too close to the house. The device can be easily attached to the bike and easily removed again. The numbers are easy to read while driving and you can change the screen to get different information if you like. I find I have my favorite screen with the information I want and I don't usually change it. The journey just loads and gives me a street map with my route.
