Remember those bulk Fiji batteries? They work well in these small flash lights. Always check the clam shell packaging as someone in Shipping is pilfering the battery insert and Duke needs to have this investigated. I never bothered to complain to Customer Service on the matter because of the cheap cost and why start yelling over a few hand flash lights when $4 for $14.00 is a good price. The grand kids liked the cool colors when I passed out the flash lights and have them hanging on the bed posts at home.
