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

I ride 2500 miles a year on a BMC road bike. Dislikes: Tried 2 different taillights and couldn't get it to work consistently. When it works, it's nice and bright. There's a quick calibration procedure to follow. For example: It is a pleasure to work with the company. As a replacement they offered a model of a day bot, it has 3 modes and is very bright. The bright mode is great when I'm riding alone, there are 2 other modes that are good for group riding so you don't see the cyclist behind you burn out the eyes. The charge lasts for at least 5-6 hours, which is 2 trips for me. Easy and quick to charge. I used the frame mount and seatpost on two different road bikes.
