Update by user Feb 20, 2021 this event occurred at home. Original review posted by user Feb 20, 2021 This gadget appeared to be pretty good the first couple times we used it, but FAILED at the most inopportune time! During the now infamous Texas snow/ice storm of Feb. 2021, power went out (in millions of homes.) I went to the closet to get Bulb .head, to no avail. Did not light up. I lit some candles, and opened it up to check. The batteries were completely corroded! Of no use now, and I am not a happy camper! How can I get a refund? Does anyone know?
