Just remember that USA is not native to us all... Some live in other coutries like me, I live in Norway. So I guess customer support suck for both Tekin and Hobbywing if one blows, I don't expect much in support anyway. As of now I got 3 Xeruns (1x 60A and 2x 120A), 10 Ezruns (13T 35A) and 2 Mamba Max (4600kv and 5700kv). None has been destroyed yet so i guess they are bulletproof. I order all my stuff out of country, mainly from Hong Kong or Japan.
So for me the choice is simple!
Hobbywing all the way!
