I have used this brand of screen protector before, and they work well. They are both tough and removable and leave behind no trace once removed. The only problem with using this protector with the Pearl is that the Pearl screen is slightly curved near the earphone and around the trackball. Since the protector is quite stiff, it doesn't sit flush with the screen in those two places. The protector still protects the screen just fine, but there are slight gaps. If you just want protection, this is a fine product. If you are a stickler about slight imperfections in the appearance of your BB, you might want to go with another solution.
