I used to use a zagg screen protector on my tablet. I took it off after a year. As mentioned, they degrade image quality. I use a spigen slim glas.tr on my phone and since its glass it doesnt degrade image quality at all. I saw a video of a guy who got one for his ipad, dropped it the next day down some concrete steps, and took off the glas.tr on video. The screen was shattered, and when he took off the screen protector it was perfect, no marks at all. The ones for the ipad are very pricey though. The phone ones are $30, I expect the tablet versions to be over double that. Still cheaper than insurance, but with a tablet, you dont put it in your pocket or bring it around with you everywhere like with a phone.
