The eraser is advertised as a one touch power eraser, when it's not.
I put several sets of brand new batteries in it, and it won't turn on.
I am so disappointed. It sort of drags your hand around and leaves bits of erasers stuck to your paper that I had to scrap off.
You have to hold the button continuously for it to erase and after about five uses it stopped working!!
It stopped working even after replacing the batteries. Very frustrating.
Works great, But you can not purchase more refills for this item. When emailing the company they are not very helpful. I will need to purchase a new battery operated eraser that I can purchase refills from.
