So far so good. It doesn't help me smear, but since I have sweaty/greasy hands, that's to be expected. I have a case that fits around the edges of the iPad and this protector fits it snugly. My case also has a magnetic wake/sleep cover and this glass protector doesn't interfere with that. I can also use my Apple Pencil without any problems. This will make the surface smoother and more slippery when using a pencil, so it will take time to adjust. If you have a general idea of how to apply screen protectors and some common sense, don't worry about blisters as some reviewers say. . Bubbles are usually due to user error, not the product itself (especially if the screen protector is glass; film protectors are another story, haha). I have never had a problem applying the screen protector as long as I thoroughly cleaned my iPad/phone/device screen before installation and properly applied the screen protector. That is, glue the protector to one edge first and then carefully glue/smooth towards the other edge, or glue the protector from the middle first and then glue/smooth towards the edges. Bubbles often form when the screen isn't clean enough, or when the screen protector starts to stick from the outside in, causing air pockets closer to the center. The point is, if you experience blistering with this product, it's unlikely to be the culprit and you'll likely run into the same issues no matter what brand you use. Okay, end of swear words. All in all it's very good and I would recommend it.
