Buy 3 hobbywings (for the price of 1 tekin) and never need to worry about customer service. I have 2 hobbwings, non have failed so far.

Tekin is a good product that I've used since the 1990s. If you're loyal to the brand and willing to spend 3x the cost of a Hobbywing (and willing to lug a laptop), go for it.
