Well, it does have direct motor control buttons for each of the three
motors. Bear in mind that this is, after all, a $20 device. Doubtless
they could have made it a lot fancier and boosted the price.
Personally, I'm happy with mine. It lets me do the following:
1. Run and stop any of the five programs.
2. Directly control all three motor outputs, forward-reverse-stop.
This is handy for physical prototyping, or for controlling a model
directly that's not autonomous.
3. Test for IR connectivity (the "beep" button).
4. Send messages 1, 2, or 3. That may seem a limitation, but I don't
find it limiting. What that means is: If you're running an autonomous
robot, you can send it one of three different messages without
interfering with its running program. How many different actions do you
want to send? How many can you keep straight in your head while you're
holding the remote? After all, you can always combine them 1-2, 1-3,
2-3, etc. and program your robot to respond to *sequences* of signals,
if three aren't enough.
All of which seems like a pretty good bargain at $20. I'm happy with
mine.
