Review on Boating Navigation Battery Operated Pontoon Sports & Fitness by Tim York

6 sets of these for the price I paid, that's a crazy bargain. It will be good for some night time kayaking. They are well built. The silicone helps keep the water inside, but you have to keep in mind that they aren't designed for long-term use and won't work well for those who expect them to last forever. These aren't $30 waterproof lights, but I'm hoping they can withstand splashes from more than one walk per set.
