Pretty useful if you don't have any eyebrows
I've been free handing drawing on my eyebrows for years due to overplucking until I had none left.  It's very hard to get them aligned and the same shape every day.  The worst is when your out and notice one is off from the other.  With this tool the first time I tried it I liked it!!!!  All day that day I checked and they were absolutely synced.  I'm very happy.  Bungee it came with doesn't do a lot but I hold it on my skin anyway.  For the price might as well try it.
