It is an appliance so perhaps your setup makes it more difficult to use. I leave it near the sink and just use it with my slobbering mouth over the sink. No more time or effort than flossing for me.
I will say the thing is louder than it should be. Like a damn motor boat when turned up to high.
I bought some steel dental picks because I'm so sick of having stuff get jammed between my teeth. Nuts aren't much better, they will always break into perfect little pyramid like bits that fit right between your molars and are impossible to remove with your tongue or even fingernail.
Luckily nuts are mostly made of protein so they'll digest in your mouth. Meat though, your mouth can't digest fat so you can literally have rotting meat in your mouth. It's nasty.
