I don't trust any product that is marketed to Americans and the distributor can't be bothered to hire someone with at least a 7th grade education in English to write the product info. I'll tolerate Chinglish when buying an $8.99 Hobby King lipo, but not a radio system. On a more substantial note, Walkera is known for producing cheap things, not good things. I've seen and heard more about their helicopters than anything else. Some work ok, but you won't meet someone using their products who had a choice to go with an Align or Synergy and chose a Walkera instead.
