Bests & Worsts Reviews from Amazon

I tried to use a mag light that didn't work and when I opened it up, I found the batteries had corroded dreadfully. It took treating with mild soda water to remove the batteries at which point, I found that I had damaged the reflector in the process. The batteries were Rayovac Dec 2016. A second mag light worked but I could only remove one battery due to corrosion. Again Rayovac Dec 2016. Their warranty requires sending the original packaging and the original receipt. Really, who keeps those things around for small purchases? Update: I heard back from Ray-O-Vac via email and per their instructions, mailed the damaged flashlights with batteries included. I was pleasantly surprised to receive later a check to cover the cost of replacement. Then, a couple weeks later another package arrived with replacement batteries. I am pleased with their efforts to reconcile the issue and must conclude that i must have bought a defective set of batteries.
