I'm just going to say that stinks! I would be so ticked off. I wonder if it states in their warranty that if you buy the product for less than map it voids the warranty. I would contact the Ebay store and show them the email from Hobbywing. As to other manufactures. I have used, and still use Tekin. Their products are good, and they do have a presence here. But, I am also looking to switch, possibly to R1. I can say, if you have ios for your phone, you may want to look somewhere besides Tekin. If you have an android, you are fine.
