The one at the Dollarama is better

This product would work best for people with hair on the thinner side I think. It only really smooths the outter layer of hair so if you have thicker hair you might need to separate it more. If you're dealing with some giant knots it will loosen them up a bit but won't take them out completely. It's easy to clean but the gray part comes off easily. They have a cheaper better dupe for this at the dollarama, I use it more since it has a handle and doesn't fall apart.

I found this product in my local dollar store for $3. It very similar to a larger company's version, but I believe it work quite well and doesn't pull on the hair. All in all a good on the go brush for travelling or even just school.
