I currently have a EX-5 UR (my first 2.4Ghz and first KO product) and love it! The response is fast and I have never had any issues loosing bind. I have had KO servos but have switched to Team Orion because they are a better bang for the buck. The only issue I can see one having with this transmitter is the antenna. It doesn't fold down and it is not replaceable, so be careful. The upside is it is tough and has survived being dropped a few times by my oldest daughter.
