What's your thoughts on the modern Furbies?

My kids each got one for Christmas and there's literally no off button I could find. They go into sleep mode, but that still gives them a chance to start back up if slightly bumped. They're not awful toys, but I feel like they could use better stuff for them.

I was trying to help my kids get theirs to follow directions when giving a voice command and it wouldn't do it. It either did what it wanted or said it couldn't hear me. I was speaking loud enough to be heard, so I don't know. Most of the time I can't tell if they're speaking to each other when they're facing. It just sounds like single conversations. I do occasionally laugh when it farts and says it needs to change fur. However, it seems my daughter's Furby farts more than the other ones. My oldest son's Furby belches a lot and yells like it's getting tossed around. My youngest son's Furby tends to just sing more than anything. If it really has 600 sounds, I've yet to hear them.

The other day I petted my oldest son's Furby and I swear I heard it say Furby is so sexy. It was pretty funny if I heard correctly.
