So i emailed customer service about this and this was their reply:
"Both the Bluetooth connection and our RF remotes have a range of up to 100 feet. However, that would decrease if there is interference. You can convert your smoker from Bluetooth to the RF remote, but you would need to purchase the control panel and remote. The control panel is typically $49.99 plus shipping and the remotes are $29.99, if you wanted to purchase both those, I can discount them to $19.99 each. If you are interested in placing an order, please let me know."
So I'm not sure if the RF range has been decreased since your review of 200-300 feet Bear, but apparently something is different now since its only 100ft according to CS. Now to decide if its worth $40 to switch to RF....
Personally, I wouldn't know why the RF remotes today would have less range than they used to.
Like I said mine worked at 210' of a clear shot, and more than likely good for 300'.
However the important thing was that it worked from every room in my house & on the outside on the opposite side of the house.
My RF Remote never dropped on me, like my Maverick Therms do now & then.
I would bet that the RF remotes are the same as they used to be, but the Customer Service person has no idea of the facts.
I would find a couple guys who have converted from BT to RF, and ask them how good theirs works.
