Bests & Worsts Reviews from Amazon

I have tested countless rear bicycle tail lights. No tail light so far is without problems. Planet Bike makes very good products. To be considered a great tail light a few requirements must be met: Easy, secure mounting, great optics for viewing straight on and from the sides, and a durable, quality switch. Planet Bike has a good, not great mount (the light tends to jiggle in the mount, which may simply be a quality control issue, not a design issue), very good straight on optics, and average optics from the side. Where is fails is in the switch category. I have purchased 4 of these lights, and two of them have defective switches. The light will change modes (from on to off to blinking) when you hit minor defects in the road. 3 stars for the light (very good straight on viewing, average side viewing), 3 stars for the mount, and 0 stars for the switch, arrives at the 2 star rating. They need to either use a Cateye type switch, or a Princeton Tec Swerve type switch.
