Does NOT last near as long as the original...
The refills are easy to install, but they last about 1/4th as long as the original.  For this reason, I think it's probably better just to order a 'new' 'guard your ID' and skip the refill.  I like the idea of not wasting materials, but I'm not sure you are saving anything by using these refills.  I will not order them again.
