It seems a lot of the negative reviews are because it didn't work. I've bought 6v batteries from several other well known brands with similar ratings and was surprised that some people didn't realize they had to remove the plastic cap from the center spring contact... so make sure it's off before using they throw in the flashlight. I don't really like them but if I can get them for around $5 I think it's a steal compared to what they want in home centers. I've converted a few flashlights to use four D cell batteries and it's a lot better for me and once you get past the initial adapter investment you can offset it with rechargeable batteries. This works for me and my flashlight is usable now.
