The User's Review: Osram Sunnyboy, the most compact electric flash with a standard hotshoe, which I have seen so far

It came to me within a camera kit that I was interested in. However, once I saw the boy, my eyes were attracted by it.

Its guide number is 12 at 100 ASA/21 DIN. It is powered by one AAA battery, with 10 seconds as its recycling time and ~100 fires on each battery. The flash has a ready light indicator by its switch on the back.

I love this boy, made in Hong Kong.
