Rc tank ordered for son's birthday present, corroded pins in track caused failure on first use. Sent back for repair. Returned in damaged state so I asked for a refund or new tank. They refused to cooperate so I got my credit card company to do a chargeback. Nitrotek sent s courier to pick up the tank and then issued a summons to take me to court. I attended but they didn't. The case was struck out. Barge pole.
