The review refers to both the 25 and 30 cm Stellar Solar Ball that were ordered together and eigesetzt: Delivery took place as usual very quickly from Amazon. The supplied Erdspießchen turned out - as already criticized in several reviews - as a bad joke, since they max. 5 cm rise in earth's. We'll see what happens at the first storm with the feathery balls :-(. Once I wanted to start with guaranteed full battery, I screwed the balls to load fully in the external charger the batteries. And surprise: This is NOT as described by AAA batteries, but shorter pieces that do not fit into a standard charger for AA / AAA batteries. Fortunately, I have a charger with flexible length adjustment. Probably is AAAA batteries (there is nothing on it), which is certainly not facilitate a possible replacement. Here the product description is definitely wrong! On the packaging of the solar sphere lit for 5 hours is indicated (Why is there this information is not in the product description on Amazon?) And now follows the positive surprise: in full sunlight during daytime lights, the balls> 8h. Bin on the burn time in overcast / Winter excited (when the balls were hitherto not gone with the wind). The illumination / light color, I feel very positive and the balls do really well in the garden. Due to the "kebabs" and the inadequate description there's unfortunately 2 star deduction.
