I purchase the mag-lite rx109 heavy duty rechargeable flashlight from Amazon about two year ago upon recommendation from my son-in-law who be a airline mechanic . it prove to be a awe inspiring product ... ... . for about the first month . Super bright with a wonderful adjustable focusing\/spreading beam . I be enthral . after the month honeymoon , reality set in as in as its ability to hold a charge rapidly weaken . soon , when take it from its charge cradle it would become useless in a matter of minute . I buy two more rechargeable battery , at twenty buck a pop ... ... ... ... . same result : take it out of it be charge cradle and all be fine . five minute later no light at all . during that two year , all I have use it for be occasionally go out with the dog at night and during infrequent power outage . it look just like it come out of the box , not a mark or even a smudge on it . there be no way the flashlight use could have exceed five hour . despite its very limited use , I still go through 4 replacement bulb at five buck a pop . along the way , the switch stop work ... in the on position . one still could turn it off and on by unscrew back a half dozen turn , but ... ... . . do the arithmetic . at 95 buck cost new , plus 60 buck in battery plus 20 buck in bulb come to $ 175.00 for 5 hour use work out to $ 35 per hour ... ... for a flashlight with a broken switch and will not hold a charge for five minute . I also have ANOTHER Mag-Lite , this one a three d cell model . with even less usage , it sit worthless on the shelf with a switch break in the off position ... . .
