I don't know why, but these seem not to work in the electric stapler as well as they used to.

In my experience they often don't work as well.

When I buy a product I do not expect nor in any way desire it to be covered in advertisements for completely arbitrary and unrelated goods and services.

We have tried other staples but they just didn't work as well

These staples work any well in this stapler and I've noted that off brands seem to cause a lot more jamming than the brand name do
