I love the ability to update the speed control by just plugging it in. So quick and easy. I do think that Tekin could have done a better job with the interface. It looks like they tried to make it really hight tech looking, but instead made it super hard to read. the colors, black on dark red make it really hard to see your picks. The slide out for versions is a black letter on black/dark background, pretty hard to see. Could easily be better. Still really like the Tekin products and have standardized my 1/10 on them. Cant beat the ability to update your esc instead of having to buy a new one. When I am keeping 3 or 4 cars running that is a great advantage.
The CC interface is much easier to use even though it is a simple box on a page type input. Clear inputs and easy to read.
