At first I did a little skeptical of the price, but the product exceeded my expectations fully met. Even the solar panel charges even in low light (of course within the framework of the incidence of light) the battery still neatly on. About the quality of the supplied battery pack I can nothing to say, since I use basically own cells and such, beiligende products generally offer someone in the circle.
In the dark, already looks alone, the amount of radiant LED's class - so far is no failure recorded.
