I have had this Product for about 7 Weeks now, if like me you have Lot's of Battery driven Gadgets ( Camera, wireless Key board & Mouse, various torches & Lamps ) this is the product for you, It Takes about 2 weeks to charge all ten Battery's. Mine are Uniross AA 2700mah and Uniross AAA 1000mah for those people that don't have Lot's of spare Battery's you can charge them 2 at a time that takes less Time.
The only downside is that it does not have an outlet to charge other devices (Mp3, Mp4, Mobile phones etc ). so may be later on they may release a product that does.
I placed mine on my upstairs bedroom window sill facing West The 7 week's I have been using this device it has been pretty over cast and cloudy.
so over all I am pretty impressed.
