My office orders these white out liquid paper dispensers all the time. I use them on a daily basis. They are amazingly useful...until they break. And that is why I am writing this review. This Papermate brand is so badly made, that the dispensers keep breaking. The last one I used broke the first time I used it. The small plastic part where the strip comes out broke off entirely. Most of the time, the big problem I have is that the strip inside the dispenser gets tangled, and thus the dispenser no longer works properly. I have not had any problems with the the Bic brand so far. I have asked my office manager not to buy this Papermate brand any more because there have been so many problems.
