I bought 2 for $31. I estimate they are worth about $3 each. Light is not bright, even with new battery. They remind me of the penlights with the weird looking E10 incandescent bulb. You can find much brighter, higher K penlights that use one AAA for much less. I am guessing these were overstocks or units that did not sell. Live and learn. I am done with "Drop".
RKP000I don't think that these are supposed to be very bright - in a medical use situation, too much brightness can be contra-indicated. Brightness isn't the only measure of the value of a penlight. So, I didn't learn anything useful from your review.
RKP000You, like I, got it for the entirely wrong reason. It's garbage for an EDC light or anything where you're looking to have bright light. It's basically only for situations that you want to look into somebody's body.
RKP000I hate it when people give products bad ratings because they want it to do something it's not intended to do. With all the flashlights that they sell that are intended for EDC, you buy one that is for medical use. Not very smart.
