I work from home and this would be cool to communicate with my kids when I'm on a call before they barge in asking questions. HOWEVER, the price is WAY too high. This is at most a $50 dollar thing.

Don't you already have a door? With a lock? A mute button? OK, maybe those aren't cool, but don't you have a piece of paper, pens, markers and some time to design your own DND signs with your kids? $50 still seems like a lot. We don't have to buy something to deal with every little inconvenience in our lives when what we have on hand + maybe a tiny bit of creativity can probably suffice.

I got a 2-pack of do-not-disturb doorknob hangers (similar to the ones in hotels) from Amazon for $10.

Worked great with my kids for 2 months. Then they got used to it and barged in anyway. The same would happen with this gadget.

And that's what makes it Juicero level.

This is the boutique designed not-in-china version. If it proves successful, a $50 Chinese knockoff will be along soon enough. You can vote with your wallet and say fuck these guys for having a good idea and working on it and buy the cheap Chinese crap version when it's available if you'd rather.
