Problem is people are using the product reviews to JOKE about the product. In this particular case, any useful info like does it work with a particular make/model is buried under jokes. Maybe it's just me but shouldn't product reviews contain constructive comments about form, function, construction, or vendor problems?

I usually find it's effective to look at the spectrum of the ratings & especially look at the low ratings. A review that tells what they like about it (does it work) and what they didn't can a big help. Several times I've decided against a product that's got a majority of 4-5 stars due to several 1-3 star ratings. Lower ratings usually describe what doesn't work or problems with a particular vendor.

It is not a good place to find deals on bulk Streamlight brand cr123 batteries (vendor/QC/old stock problems).
