We tried three different collars for my father. None of them were comfortable or useful for him. We had high hopes. They all "clamp" his mouth shut, so talking and eating were not an option. A head is very heavy, and for all of the weight to rest on a "thing" was just too much. The best thing we figured out is rather primitive, but works the best for him. We tie a strap (like a bathrobe belt or something maybe about 6 feet long) onto the wheelchair back, wrap it around his head, and tie the other end onto the wheelchair back. It gets uncomfortable after about 20 - 30 minutes, because it's tight on his forehead. This is how he eats. He doesn't have bulbar symtoms, (I don't think) but he cannot support his head at all, so it hangs down and over to the right. When he's sitting up at the table and wants to talk or eat, this is what we do. I'll even do it at a restaurant. It causes people to give a second look, but it works. MH
