Dry erase boards work much better than the standard blackboard since you don’t need to get your hand all chalked up whenever you erase whatever’s written on it - not to mention the ugly and unergonomic design the blackboard eraser has, and this is where the Ultraser comes in. It is actually a plastic disc with a really large handle for easy erasing with a dry eraser underneath doing all the work. Sure looks like it has a bigger footprint to get rid of all the written “data” much faster though. Not to mention it makes a pretty good anti-talkative student projectile while you’re in class.
