Thank you both for the input on this flashlight as owners 
SKV89, the same thing happens with the TO46R and the TO10R, sometimes the buttons are hard to find. On the 46R, I put the clips towards the top in the direction of the switches, and on the T10R I added a clip too, to make it more carriable and also due to that.
I believe the E05 is the one that solves those issues with a fixed clip 
BurningPlayd0h, that is weird, I guess I didn’t read anything like that before. Maybe a defective sample (driver or switch)? About the price…it is expensive. I cannot say if it is appropriate or not, but maybe the reviews help Wuben to adjust MAP values in case it its needed!
Thank you both for your contribution on this!!
