Petzl Zipka Plus Review

"Its on its way back. The electronics causes the light to cut off after the battery power gets low. The new pushbutton switch, the 4 led's, and the lip cutting glare from glasses was a great improvement over the regular zipka. But, the older models light would just continue to get weaker and not just cut off all of a sudden. I now use just the heavy Duo with a 5 led conversion or my old 3 led zipka, better safe than sorry."
