def. junk, i agree with that opinion.
just picking up my thermometer makes the screen go wild. i had a controller laying around that i hooked up recently. constantly reads pH and temp and prob. doesnt get much more accurate then that.you can even plug your heater into it and it keeps it at that temp. im not saying invest this much for a thermometer but its an option. i want to say they have larger size glass thermoms that have bigger numbers on them but im not sure.
