I just got this today and tested it out, this is one of the most magical pieces of machinery the world has created! With a 4 month old it’s not the easiest to get time in a day to go and get my eyebrows done as often as I would like, this wonder stick has just made it quicker and easier to do a perfect clean up. My hair grows quickly and it’s thick, this bad boy managed to go thru it with no issue at all. Probably won’t use it to shape my eye brow but def perfect for a clean up
