Дешевый и нет ничего лишнего.
CONS
При 1 литиевой банке не выдает номинал. Максимум 0.63а
Неплохой драйвер, но не раскачивается на указанный номинал от одной банки лития. И это как то удивляет, ведь драйвер примитивный как лом. 5в - строго 700ма. Что здорово - 1 режим.

Works just perfectly if you need a 1-Mode 700mA driver.
CONS
Looks a bit cheap, no positive contact-spring
It draws a bit under 700mA (4.2V / 685mA measured with bench power supply) and does what I wanted it to do: It drives a 3W UV LED in a flashlight.
