Yeah, my wife called me on her cell phone because she found the "yellow" can but they all said "dif" in them. Then she reached in the back and pulled one out that looked like an older package and believe it or not, it was the "Tetra" one!
The "dif" cans has it worded in super small print in the "do not use over this temp" warning paragraph. The "Tetra" can has it printed in red letters in a different spot.
It is obviously the older version that still contains the "tetra" because the .pdf file on the website warns of it!...crazy...
