I feel slightly stupid...
I feel slightly stupid for my last review for this (On the pink one).
It was really really nice, but sadly started not functioning and growing dirty
and just wouldn't come clean.
The erasers last long and are great. But do smudge a little before erasing.
When you push the tip down, usually too much or not enough of the eraser comes
out. Sometimes (Because I push it gently back in before putting it away) it
takes a million clicks before it comes out!
Don't know about the other pen style erasers, but what your getting for the
price is what you are getting.
