Review on Supershieldz Tempered Glass Screen Protector for Lenovo Chromebook Duet 10.1 inch - Anti-Scratch, Bubble-Free Design by Terrence Tucker

This protector fits the tablet very well - the camera notch really needs to be a bit deeper to ensure perfect centering, but in practice it doesn't matter much and the tiny offset is imperceptible. Installation was easy and the optical quality is good (much better than the plastic protector I used before). I have an HP USI pen that I use with the Duo and I don't notice any difference in accuracy or alignment with this guard. So if you use a pen, there's no reason why you shouldn't get one. A tablet without a case is so light that the weight of the additional glass is noticeable but not annoying. I think if they give me software updates for 8 years I might as well try to keep the display in good condition so this protection seemed like a good investment to me.
