The powder seems to work well but I am only 1 month of using the product and have some more on repeat.
The reason I have only gave 4 stars is the fact that the little scoop provided basically sits in the powder so it ends up being buried meaning you have to dig around to find it which is annoying and messy.
I’m sure it would be easy to put a clip on the underside of the lid to attach the scoop and then you have a 5 star product.
