Query: Undone by crummy temperature probes

It's convenient to be able to monitor the temperature of something being grilled remotely. It worked very well for grilling a turkey. But the probes that come with it are very poorly made and only lasted 2 uses. They do not survive actual grill temperatures. There are supposed to be higher temperature probes available that work with this unit. I've ordered some and will see if they work better. The ones that come with the unit are worthless.
