Wish mine had worked as well as yours. I had that same one and it didn't even last a day. Worked for about 15 minutes before the remote part died all on it's own.
I currently use a very cheap digital in my GOSM for the smoker temp, and use a Polder for the meat temp. The cheap one has lasted several months, but I tried to use them for meat temps and have gone through 2 of them in the last few months as the probe is not very well made and the wire eventually ends up coming out and giving wrong temps. Since I do not mover the Smoker temp one, it has lasted quite a while.
