I wish. Mostly it's switches. Sometimes even the light assembly pops out. More rarely the front spring thingy on the battery holder. I have a can I toss the carcasses and every once in a while I'll try to make a couple working ones, but it's really not worth the effort. I'm pretty fond of the $9 ones from Homedepot. I like them a bit better than the Costco set because they don't have that dam flash mode. That really kills my vision at night.
Yeah, actually I got some of the FAR ones from Ace Hardware on the After Thanksgiving Sale last year. They are much, much better than the Harbor Freight ones. They have the same amount of LEDs but the light is so much brighter and more focused.
Hopefully they'll have them FAR again this year!
