I purchased a Zagg invisible shield hd clear for the iPad Pro. I am pleased with how it works as a screen protector, I did wait until my pencil arrived before I installed the shield. I can say that it works very well with the pencil as well. There is no lag and the line quality in the procreate app is very good as well. I did heed advice I had read and applied a copious amount of application solution. I did not use the iPad until I let the solution completely dry. I am very pleased, to date, with this product.
