I don't use their cables but I've had their LCD heat controller for a few
months now. My venerable 1991-vintage Dupla controller had some problems of
late. I believe the technical term that explains the problem is "going
wack-o".
I'm very impressed with the M3 controller - very solid unit. I have it set
at 76 F with the recommended minimum 2 degree differential. I've not seen
the water temp differ by more than +/- 0.5 degree as measured by an
independent digital thermometer.
Two thumbs up.
