Homeland Housewares, the company that makes the Magic Bullet blender, sells replacement parts on Amazon, but does not sell the gaskets individually. Shoppers can either buy replacement Magic Bullet blades, with the gaskets included, or buy gaskets compatible with Magic Bullet but made by other companies.
If shoppers want to buy original Magic Bullet replacement parts made by Homeland Housewares, they should read the product details carefully. A number of products that are sold as compatible with Magic Bullet have the words "By Magic Bullet" under the product name on the search results listing page, but the details include a disclaimer that the company is in no way related to Homeland Housewares.
Shoppers who are willing to buy compatible parts made by other companies can save some money, but may want to read the product reviews before purchasing. As of February 2015, 500 reviews on a pack of four replacement gaskets for Magic Bullet sold on Amazon by Fab International included 286 five-star reviews and 73 one-star reviews, with a lot of mixed reviews in between. While many reviewers write that the replacement gaskets worked perfectly with their blenders, other reviewers said the gaskets were poor quality and did not fit well.
