Yes, this description doesn't say anything. Hard to sell something you can't market. I only found out what it was because I went to your website.
The idea is good but I don't see people buying this. Who's gonna have as a priority in their day to carry a "bathroom door locker" (that's basically what it is) in their bag or pocket?

Who's gonna say "oh my god! There is a chance I may need to go to a public restroom when I go out today. Let me take my bathroom lock with me in case one of the doors can't be shut".
