Query: Do not waste your money and time

Bought this item from a local store. Inside the cheap plastic housing, there was a pack of 4 AA-sized rechargeable batteries. But it's okay, there's only one LED.Charged the battery for 3 very bright days as the instruction manual said. Then what happened? The light never turned on while I tried many different combinations of the three adjusting knobs.I returned the item for a full refund, but I incurred a loss for my investment in extension wiring with matching connectors for the best sunlight exposure.
