Basically, the torch fulfilled its purpose and has a big plus, the small size. They can, for example, wear loose in your pocket without bothering them. But it is less comfortable to hold than its predecessor, which unfortunately died after about 6 years. This was about twice the size, made of plastic and had a very pleasant rubber coated handle. That SFL4100 Metal is, I do not only because of the feel as a disadvantage, but also because it is thereby difficult. An advantage I do not - because what good is it if the housing "unbreakable", but LED and electronics are sensitive.
But the big disadvantage of this lamp is completely impractical placed on / off button. It is located on the front side of the handle. Thus, it is not possible that one holding in his hand the lamp switched on or off with your thumb. One needs the other hand to. Complicated as it gets.
