So after using it for a week, I LOVE it, and i really like the setup that im using. I use a 30,000 mAh battery that is in a bag above the bike's battery, it is protected from the elements there. the bag has a design to allow cable to come out (for headphones) so that is where the usb for the power to the device goes into the bag. I spent a week trying different connecting methods. This is the one i am most likely going to go with. The mount that holds the screen clamps onto my extended bike bar, and the mount has ball adjustments at the bottom and top so i can really get the screen to where i want it.
During the day it is pretty hard to see the screen at times and i just use the mirror. At night though i really like it over the mirror. There are times when i am not in my normal riding position (like when climbing hills, i go from upright position to a more normal "biker" position and my head goes towards the handlebars and using the mirror is not possible, so having the screen to see is really nice. I know that at night i can pretty safely see my back when looking at the monitor. It also is pretty bright at night in dim situations.
But the best feature is just having it auto record. With the 30,000 mAh battery i was able to make it the whole week while riding about 20 miles a day, everyday. When using the battery pack, i was not able to turn the system on using the power button. I had to open the bag where the battery is and hit the power button to turn it on, and the system auto turns on and records. Slightly inconvenient , where i would prefer to be able to hit the power button on the device and that would wake up the battery but i get why it doesn't work like that. I would seriously consider hooking this up to my bike's battery or controller if it did not void the warranty which i think it would. Only other downside was that there is no way to turn the screen off that i can find. It has a "screen Saver" mode but that just shows you your speed based on the GPS and its a bright gray screen. Sometimes i would want the screen off or hidden, and that is why i think the mount that i picked is best. I can quickly adjust it so the screen is facing down towards the bluetooth speaker that is below it, i could do that when im going into a store for a little while or its annoying me. Also i think sunshade might be helpful.
