Review on 🚦 Enhanced Safety with Portland Design Works Gravity+ 100 USB Tail Light featuring Accelerometer Technology by Chris Long

Nice concept but I'm not sure if the product works the way the company intended. The very small LED light is just ridiculous. Flashing light is ok. Not sure if the light works like a brake light when stopping. Considering it's a taillight, it looks like the mount could have been for more than just the seatpost. I have a rear bike rack with panniers. The light is not visible from the seat post. Also, there is no room in my saddle to mount a light. Hopefully the company feels that not every seatpost is a good place to mount a light.
