You get what you pay for
Frankly I’m amazed about all of the super good reviews on this product. As the headline says, you get what you pay for.  They look very summer to the Oral B product.  Unfortunately they are not made tightly.  When I use one they pinch my lip because they are not tight up against the base.  The good news is they don’t cost a lot so when I threw them out it really didn’t bother me.
