It's the same wireless as the Weber. It only has preset alarm temps for specific types of meat. You can usually get a temp that is close to what you want, but maybe not exactly. It is better suited to grilling than Q'n. Makes a good gift for someone that grills occasionally. I bought one last year, or the year before at a great sale price around this time of year. One day I'll either use it, or gift it.
Don't bother with the radio shack model. I bought one a year ago and it didn't work out of the box. I took it back and they exchanged it. The second one went out on the next cook. Midnight cook at that. I was working about 5AM and at 7 it wasn't. I ended up trashing it and buying the nutemp and haven't looked back.
