If you know how this works, feel free to ignore my attempt to describe it to consumers like me, who ordered it blind, or solely on the basis of an overall positive recommendation from reviewers. As the picture illustrates, you receive two phallic-shaped objects--one for regular sockets; one for smaller, candelabra-type sockets. Each is coated with a black, rubbery prophylactic tip, which you insert into the appropriate socket with the broken bulb. The smaller tip is inserted into the larger tip and has a single screw for fastening: 1. the assembly together and 2. either of the tips to a long extension rod (not included. but available from Amazon) for reaching ceiling lights. That's the inert gadget, ingeniously configured to enable two sizes to take up only as much space as a single size. The design also eliminates the extra screw so that the owner is protected against the loss of one size when he needs the other. Now comes the interactive part of the puzzle: the challenge of unscrewing the base of the broken or burnt-out bulb that has been left in the socket. Nothing frightens me more than replacing a bulb above the landing between the basement and the main floor or the main floor and the upstairs. Upon climbing my aluminum step-ladder I look down to briefly assess the danger should I fall not merely to the floor holding the ladder but to the extra story that's directly underneath the ceiling light socket. Contemplating the degree of injury from falling two stories--possibly hitting a bannister, a Grandfather's Clock or a stair-rail on the way down (whether one or all three)--is an altogether chilling prospect. In any case, I began my vainglorious attempt to unscrew 3 dead candelabra bulbs in the ceiling fixture of our entry-way. I broke the bulbs and began pushing and unscrewing (turning the Bayco device counter-clockwise). I had assumed the rubber tips would be sufficiently turgid, or solid, to permit leveraging the action with as much the arm and shoulder strength as I could muster. Not so! The tips are more like a balloon--thick-skinned but collapsible with minimal pressure--than a hard rubber surface that can be pushed against with enough pressure to unscrew tiny bulbs from their sockets. Continuing with the descriptive imagery in the first sentence of my 2nd paragraph (above), I might conclude with this assertion: a rubber tip that goes limp is a bad bet for insertion. As a result, this aid, however ingenious, is as prone to failure as to success if the goal is rebirth of an illuminated light fixture. I'm hopeful that Amazon will show some bright, attractive and, above all, easily mountable new ceiling fixtures. Two happy endings: 1. Amazon has a handsome fixture that accepts two ordinary 60-watt light bulbs--all for $12.95. I quickly ordered one. 2. I continued to play with the Bayco changer until I had hyperventilated long enough to conceive of a better device and M.O.--one capable of producing "forked lightning!" Noticing an old, thin table fork, I judged it about the same size as the base of the broken candelabra bulbs in the ceiling fixture. So after grabbing the fork and finding a rubber glove, I was back on the step-ladder, forking around until I had unscrewed each broken base and replaced all three. I flicked the switch and voila! The radiance of those 3 little overachievers was more thrilling than any civic fireworks display. I'm keeping the fork (but without patents). "Shark Tank" continually awards cosmetic collectors, baby bundlers, extreme athletes and foodies. But the show seems short on products for the ever-growing pool of retired homeowners.
