Rather than toy flashlight

I am well aware that I will reap the same with this rating "negative comments", but want to point with this 3 * rating potential buyers on the effective size of the lamp.
I have let myself be unfortunately by the original image and the many 5 * ratings dazzle and could nowhere be seen that in this flashlight (probably due to the mini size) only small alkaline (button cells) can be used. In particular, for reasons of environmental protection, I find that this is no longer appropriate and should start with a Lamp size (AAA, etc.) can withstand a re-chargeable battery.

Let the light output for the size of this flashlight also be nice, so I look at it myself rather than (the size of a little finger) toys.
