I got these to work, and I like them...

Reviewer: from colorado rocky mountains, driving all over the USA

I'm using obsolete Parallax (SX-28) microcontrollers (but I assume they're all about the same)...
--- these were tricky. I kept getting no response except for the reset. Finally I set up some LED's and just observed (sampled EVERY TWO micro-seconds) so that I could see the unit's responses --- it was faster than I had ever expected: my program had been too slow. I then programmed my "sampling" right into the middle of those observed responses - and the units work really well...
--- also, they usually take another reset for a another function to be performed...
--- I could query each unit's serial number, (and write it down) so I didn't have to bother with the CRC; instead, I just ignore (try, try, again) any response that is not approximately what I was expecting.
--- "everything" is inside the simple, 3-lead chip -- so I will use the cheaper single chip -- I do not know the benefits of the same chip mounted on a card for an extra $4.
