The different modes can be actually carried off easily by head pressure. This is noticed with somewhat why I initially can only awarded 4 out of 5 stars. If I lightly press the button for the different light intensities I get though the audible feedback from button I have operated this, but the mode does not switch to the next light intensity. To really get ahead I have to press the head with a lot of pressure. I do not know whether this is normal or I have now been unlucky with my model.
Otherwise, I can only say that they are with normal AA batteries running incredibly bright for an LED flashlight in the strongest mode. There really needs not even the Strobomodus to other "blind" to bring.
Had this weird thing with the button I would not give smooth 5 of 5 stars. Perhaps I can have someone who they say if this is also possesses normal.
ADDENDUM: Have the flashlight exchanged and now the problem is not with the fashionable age. So was actually defective.
Now I can give 5/5 stars
