To go into a little more of what Marty said is the info commercial that is being played is the same company that we are a distributor for. The models that they are selling on TV are made in China while the ones that we are selling are made in the USA. That said they are both about the same except for the material and where they are manufactured. It makes about 1/3lb burger.
Works great for camping as well - I will make up stuffed burgers ahead of time with all the onions, cheese, pickles, and bacon - then this way I don't have to pack that for camping, it is already in the burger. I will make these up in big batches and freeze them as well!
Mushroom Swizz Stufz
Another favorite of ours is using chopped up cooked bacon, red onions, and some blue cheese. I thought I had a pic of this, but can't seem to find it.
These go right from the stuffer to the grill - no need to wait for anything.
One more last tip - if you add say a tbsp or so of Heinz 57 sauce to your burger and mix that up before using the stufz it tends to form a little easier in the burger press. And they clean up super easy!
And don't forget Cordon Bleu's - use ground chicken or turkey instead of beef! Roll in a seasoned panko or bread crumb when you take it out of the Stufz. YUM!!!
