Hi Tinderbox, pretty sure the raised blue button is only on the older models, the newer stuff has the black button like in the pic, have the S10r that has the flat black button. (Button like pic is great)
Have got an S1 mini that also has a black button, its prouder than the one on the pic and is a bit of a softer rubber,
If you buying a new light am pretty sure the blue buttons are history, didnt like them anyway.
give supplier a call or email them before you buy it.
