Great concept, but failed miserably - Lightstar Ministar31M-EX LED Conversion Kit - Flashlight Head for MagLite 4-6 D-Cell Flashlight

No matter how I tried, no matter how many times I reread the sparse directions, never got this kit to work. I have the 5-cell Maglite, and thought it "fits" it never actually worked. I tried with all variables ("switch" in various positions, bulb collar on, off, o-ring in or not, yet, without success. If this DOES work, I'd love to hear from someone who figured out what is missing from the instructions! Nothing telling me who to call if I have issues. Cost about as much as the original flashlight, with works just fine. Not impressed.
