Now this works like any old dry erase eraser, the side that actually erases seems a bit cheap and so does the build quality, but heck for this price

Expo 81505 whiteboard block erarer works excellent with the U

These erasers work very well on the whiteboards I bought and don't fill up with the marker junk

Seems to have worked well so far.

This dry eraser works well and is good quality.

This dry eraser works well on the white board that we hung in our grandchildren's room

Good works

Nice product that works!

This works great with a standard white board, but does not work well with sticker-white boards or whiteboard paint

This eraser is a great price and works to get the white board clean.

Great, works good

It reall y works good
