ZX-35850 (Hercules Unbreakable 3.5CH RC Helicopter) – Ordered using groupon code, but it did not go through and have to pay full price. I thought its ok and opened the packet. Did not assemble the helicopter, but first tried to use the adapter and charge it. But the adapter light does not lit nor it charged the helicopter. So now it is time to reach customer service, but it was so hard. Left voice messages, but no one calls back. Its been one year I had this product, but I am writing this review as was cleaning my garage and found the nicely packed helicopter which does not work. I will never go back to them again nor suggest anyone to buy anything from them.
