Yeh saw that in the warrenty, might stick to it if its not too costly. Good to hear they bounce ok and it didnt break! Merit plugs are good, the feedback i saw said to getrid of the normal ciggy plug fitting, I think as long as it cant shake out of the socket is the main thing. Chuck up some temps and what setting youre dial is on to compare! Doing one today in the back off the car, put some frozen stuff in freezer and milk etc in the fridge side, ambient is 30.6 and im'e on no. 9 setting and freezer is only at -14 ?????? Going too leave it abit longer to see whats happening. Last test inside on 240V (which shoulnt differ cause the transformer turns it too 12V) same ambient setting 6-7 had it at -18-19.
