Being a conscientious mobility scooter user [use due to severe mobility issues] I sometimes encounter incidents where people are truly inconsiderate - parking fully on pavements, turning corners without indicating, cutting me up when I need to use road or when they are on foot and other issues. I was getting verbal abuse and threats of physical harm over such incidents or simply as I was seen as an 'easy target'. So I started using a car dashcam with 3D printed housing and usb power [bank]. People back off as soon as they release they are on camers ['dascam'] and the footage can be used as evidence too.I bought the YDI Motorbike Dash Cam to fit to my mobility scooter in place of my 'knocked together' camera solution. I'm very happy with my purchase. I fitted the device[s] very easily and found the colour coded wiring particularly usefull. The camera image is as good as expected and recorded images are great for this type of device / system. It took a few minutes to scan the included instructions and a very short time to get used to the controls. I have only had chance to try night vision in a totally dark garage and it looked great. Audio records really well also and the GPS gives me an on screen speedometer that seems accurrate.I cannot comment on how well system works if powered from bike directly as I have only used USB powerbank to power device. I can report that I live a mile and a half from town and have easily gone to town, gone around shops then reurned home after some hours 5 times before recharging the powerbank. Before purchase make sure any powerbank you may want to use will be adequate - product info gives guides to this. My only gripe is with the display - it can be hard to make out the image in daylight even when not so bright. The issue seems to be with 'glare' and the screen acting a bit like a mirror. I intend to combat this issue with an anti-glare sreen protector cut to size if need be.
