We recommend replacing the Banisher 1.0 after 3-4 uses, since the bristles can become dull where it won't be effective anymore, and there may be a risk of infection to the skin from previous uses. Typically the roller will last about 2 months with proper storage and cleaning.
The newer Banisher 2.0 version lasts twice as long, and we recommend replacing that one after 8 uses.
The Banisher is also sold separately if you don't want to repurchase a whole kit.
For our repeat customers, we offer a generous discount on the products for future purchases.
