Coospo TR70 Radar Bike Light

I recently picked up a Coospo TR70 Radar Bike Light to use for my bike riding, specifically for my commute to work since it puts me on a few roads where there can be heavy/fast car traffic, mainly Hampton Avenue through Milwaukee, Butler, and Menomonee Falls. Matt has a Garmin Varia and I thought about getting one but I still get nervous spending over $100 on something. The Garmin Varia is $150 USD while the Coospo TR70 is $70 USD. That half-price deal really got me interested, though I was worried about quality, especially with the app, since I use my mobile instead of a cycling computer. Oh, Trek also has their own, the Trek CarBack, which is $200 USD, which is even nore expensive! But does have the best name. Okay, so how well does the Coospo TR70 Radar Bike Light work? Before I got it I read a few reviews, watched some videos, and now that I’ve used it for a few weeks here are my first impressions, though obviously I don’t have any other units to compare it to, so this is more…
