The Strion LED is the best light I have ever used, and I am a flashlight nut. A charge seems to last forever, it is crazy bright for it's size, and is light and compact. Mine has already seen a fair amount of abuse, and it has held up great.
Several associates of mine have recently purchased the latest Stingers, and I can't figure out why. They are big, bulky, and heavy compared to the Strion, and are no brighter.
The problem of accidental activation mentioned here earlier may be due to the type of case used. I carry mine in an Uncle Mike's Mirage case, and no problems whatsoever. I carry mine offside behind the hip, and it draws quickly and easily.
The strobe feature is also a big plus. I have blinded aggressive subjects with it, and they tend to back off. Also good for traffic safety. Just don't aim it directly in the driver's face.
The ONLY problem with this light is that it wasn't available in 1985 when I started my career.
