It's just a rebadged hobbywing. I had an 80 amp and it was junk. It was ok when it was working but I have had nothing but problems with it. It fried after about 7-8 packs with a 1600kv motor. I sent it in to china for a total shipping price of $55 and they sent it back still broken. They at least refunded my $33 shipping cost from them to me. Also it's HUGE.
