As for the Wons, what I like and what I don't like...
What I like:
Titanium is hard as nails, no worries about fish breaking them
Temperature controller being separate makes changing temp easy
The ones with digital readouts double as a thermometer
Titanium shell of heater is grounded, so you get grounding rod function as well
Electronic controls are less likely to stick "ON" than "OFF" (sticking off is safer, IMO)
What I don't like:
Horror stories about about these things. I have Wons on 3 tanks and Jagers on 3. I am slowly phasing out my wons to Jagers over fear of disaster
While they are less likely to stick "ON" than mechanical heaters, they are WAY more likely to stick "OFF" (I.E. stop working). I've had two go out on me in this way. Never had one stick "ON" and cook my fish though.
I totally agree with every point that SCSI made.
Wow, you really covered that well.
