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

4 year ownership approaching. I drive on a very busy road and at the same time - I have two rear lights. This light, while not as bright as some of the others, lasted until the other two failed, one stopped working and the other broke its mount. My current second light mounts on the seat support system which gives good light but needs to be charged at least 5 times as often as this light which is inconvenient. I recommend this flashlight because my neighbor claims he can see it from a great distance, the exceptional battery life (compared to the other 3) and the fact that it's still working after almost 4 years.
