You know that saying, you pay for what you get? Well, I learned the hard way with important documents that you definitely should pay a little extra for the better white out. I've used some other cheaper brands & found the erase strip breaks & tears while applying it to the mistake & you have to go over it a few times, making the area bulky. When I use the Liquid Paper Dry Line it goes over the area smoothly & with just one stroke I get the area. Also there's no need to wait for it to dry. The only thing is that if you use pens that are free ink roller ball types they tend to get stuck or something when you right over the whited out area. I use a regular ball point old school pen over the whited out area. It's also good because it's clear so you can see how much you have left before having to replace it. Also this brand seems to be double the amount of dry erase than other brands. It's well worth every penny!
