Let me preface this review by saying this is a sample provided to me by Cupert Technology, but I also backed this project. To begin, the install was super simple. The adhesive is fantastic. Once I laid it down on the screen, the adhesive basically did all the work for me. I just had to press down on a couple of areas and it was all done quickly, with little effort. No bubbles at all. I would say it's as simple to install as any non edge-to edge protector. I was truly impressed. The glass is curved and is full coverage. The glass is also super smooth and the clarity is fantastic. Touch screen sensitivity is perfect. It cleans up very easily as well. It's 0.20 mm thickness is only noticeable near the home button area. It's very smooth around the home button and doesn't add very much bulk at all. I may have to adjust my install later, as I believe it's a little off. My Magpul Field case worked perfectly with the protector. My ZooGue had some trouble. I'm thinking the install is the issue with the ZooGue, since it's lip is a bit more aggressive than the Magpul's. I really don't have anything negative to say about this product. You can tell a lot of thought and effort went into creating a curved glass screen protector that's simple to install, is thin and just works. It's all very well done and pretty impressive.

I'm really not sure when it will be available to order on their website. If I should hear from them, I will update this thread.
