I purchased 51C812 Forza 2.4 G for a price of $174.65 for a Christmas present for my son. Unfortunately, it did not work - apparently the receiver was broken. I tried to get a replacement but to no avail. I called repeatedly but no one ever answers the phone. I faxed a letter and then I sent a letter registered return receipt mail and still no response. I sent many emails and never got a response. I spent almost $175 and have absolutely nothing for my money except a car that doesn't work. After months of trying to rectify this situation, I then ordered a new receiver (hated to spend more money) and sure enough that didn't work either. read full review »
