The Up and Up Erase-Away Mulit-Use Erasers do a decent enough job for cleaning, but tend to crumble apart more easier than its brand name competitor. I felt like I needed to use more of this store brand's eraser product to accomplish the same cleaning job that would have been achieved with the other product. It will do cleaning, and does get scuff marks and such off the wall, just be prepared for it to disintegrate faster and fall apart quicker, thus having to use another eraser. By using so much it kind of defeats the purpose of it being cheaper in the first place. Performance The Up and Up brand eraser does almost the same job as the brand name eraser. I use it mainly for scrubbing walls clean from scuff and crayon marks from my children. It will eventually clean the area, but it may take longer, and will fall apart rather easily. The Up and Up eraser does not seem very durable for long periods of use. Its the cheaper product and you will notice after using it for the first five minutes. Scent There really isn't a strong smell with this brand of erasers so I gave it an eight.
