Yep, you got it, I picked up both of these bluetooth thermometers for Thirty Dollars at a going out of business sale yesterday and I a not at all happy with the deal.
Smoking a pork shoulder overnight so I figure that would make for a good test.
ET-735 Screen Shots on Galaxy 7CDN Screen Shots on Galaxy 7 The bluetooth range on both is terrible. Straight line is about 60 feet. Once in the house I would loose connections on both with the CDN being worse.
Bottom line: I spent too much money on both of them.
I am happy with my years old ET 732 where I never loose a connection in the house.
I never turn it off and batteries last forever it seems.
I also have been using a Rock's Stoker for some years for monitoring and controlling pellet grills through a Savannah Stoker Controller, Lang stick burner (sold) and an Acorn (given to neighbor).
