The Castlelink itself is not a problem. I have the losi, ztw and tekin tongle as well. It's me getting to the rx cable that is the problem. Its faster to get to the ESC at times. This is where the usb port comes to be handy. This is why I also still have my Mamba Max when I feel like messing with settings, before I try them out in my rides with the MMpro and MMM. The Tekin is easy as there are two buttons on the ESC itself to deal with. I only use the Tekin dongle to make custom profiles and mess with the timing. But for the price of the Castle products you can't really complain.
