Battle of the Detangler Brushes

I was originally only going to do a comparisons of the Tangle Wrangler Brush versus the Felicia Leatherwood Detangling Brush but then I remembered the Michel Mercier brush that I purchased maybe some time last year and decided to share my thoughts on it as well. Although, you may already know what I think of the Michel Mercier brush, given that I forgot I even had it. LOL
