Review on LK 6 Pack Japanese Material Screen Protectors for Apple Watch 42mm Series 3 2, Model KO4721 - Bubble-free, Flexible TPU Film by Daniel Jenkins

I liked that there is a clear video instruction, enough reserves in the box for unforeseen situations and future replacement. The video said to install it overnight for the best results, but I only did it 10 minutes ago and it stuck to the screen perfectly. I gave the product 4 stars out of 5 because it doesn't have as much edge coverage as my previous watches. It's not a deal breaker, it's just that the extra 1/1.2mm thick exposed screens could get scratched. Overall this is a good product and I would recommend it as a cheaper alternative to Zaggs.
