The little flashlights are great but I found them difficult to handle due to their size and they almost slip out of my hand. Optimum size is at about 4" long 1" dia.
I bought my wife this little thing. Small enough to fit in her purse and not heavy. Plenty of light out put. I love the magnetic tail end. A little too small for my taste.
