We have tons of gadgets, but really use one much more than anything else. It's a "unique cooking system" for cooking over a fire pit. You drive a pole into the ground next to the fire pit, and an arm attaches and swings out over the fire. A cooking grate, Dutch oven, or pancake griddle fits onto the arm and you can move it up and down, back and forth. It's sturdy enough to handle just about anything.
We used a tripod for years and thought it was the best. This thing blows it away. We often have people in other campsites ask for the phone number to order one for themselves. We have given many away as gifts for our camper friends and everyone loves it!
The only down side is that you can't use it at FW because they don't allow fire pits!
