Hi,
I've read numerous opinions about Arc AAA-P. Good reviews, test done (switching on and off thousands time) etc, etc etc.
Got convinced, and got one for myself, even used it for something like a year.
I still find it marvelous, that nobody has ever mentioned that this little critter physically damages batteries. To be exact it works like an vise:
1. twisty switch creates the force
2. hard/unelastic contact on the head can be viewed as jaw nr.1
3. hard/unelastic contact area in the battery tube can be viewed as jaw nr.2
4. small pin on the bottom of battery tume - now this speeds the damaging process greately.
So, when ARC is turned on the battery is getting squeezed and shortened (unelastic contacts), and after some time, the battery is so short that it is unable to touch both contacts at the same time.
That's a major flaw that makes ARC AAA-P unreliable.
Of course the solution is not to twist the switch to much, but this is no reasonable solution because my hands are not equipped with a built in torque spanner, and "too much" is very hard to measure.
