1st thumbs down:The little magnet that is suppose to mount on the spokes. It has a molded in space between the 2 halves of the clamp that is so long that even tighten down has tight it would go, it would fall off. I had to take a knife and trim it down in order to tighten it down enough so it would not fall off.2nd thumbs down (and the TOTAL KILLER for me): Once I finally got it install and the arms adjusted I load the app on my phone. It rqusting all sorts of permissions, like access to my media files.Can you set the background behind it perhaps? By why my camera and mic? The killer was when I first loaded the app it insisted I reqister it, which does not brother me, but not only did it want my email address, it also insisted on having the PASSWORD to the account. Sorry, no go, no way, no how, nada, not happening. The app has been removed from my phone, the sensors have been uninstalled from the bike and I am contacting Amazon about returning it. There is NO reason for it to have to have my password, even for a moment. Nothing else I have installed and reqisiter have demanded the password, just the addy.I will not be buying anything else by this company. (The manuafactor, not the seller.)

1. The installation instructions were tiny and hard to read. Searched the internet but was not able to find any online instructions.2. The hardware requires the app "C-omnicare S". I downloaded the app to my Samsung Galaxy and every time it launched the app immediately crashed. I tried uninstalled and reinstalling the app, but the same thing occurred. I found that there was also an app "C-omnicare", which I downloaded. The application looked cool and was able to connect to the hardware.3. The hardware partially worked with the C-omnicare app. While biking, the blue tooth dropped several times and required me to open the application settings and reconnect the blue tooth. This resulted in less accurate statistics and more unplanned stops.The application did chart out my path using Google Maps, which was pretty cool.Those that have an iPhone may have had a better experience, but I ended up returning the device.

Can anybody tell me how i can connect this thing with my phone. What is the code for the bluethoot conection i entererd 1234 and 0000 and doesnt work!
