I have one and like it. The major complaints seem to be tiny on/off switches that may break easy. I am careful and have not had a problem. You have to take the battery cover off to turn on the transmitter. I understand this is for waterproofing. Again, not a huge problem. Only takes a couple of secconds. Doesn't work to 100 feet as advertised. This would be an open air spec anyways. Range is going to be shorter through walls, doors, lead plates, etc.
Difficult to program.
I don't really think so. Not super convenient to go all the way around the numbers since you can only adjust it up but not the end of the world. Difficult to get units to link. Turn on the reciever first then the transmitter. I've never had a problem. Can't really think of anything else.
The one complaint I have heard that I do agree with is it gives no audible signal if it loses communication so you have to be real careful if you're roaming around with it. I set mine about 40 feet from the smoker and it reads through a sliding glass door so I've not had the signal dropping problem that others have described.
It's not perfect but for a dual probe model with high and low smoker temp alarms (which is why I bought it) it does the job for me. If anyone spots another model that is dual probe with high and low temp alarms, please let me know.
