Bests & Worsts Reviews from Amazon

This product is incredible! I used it on my Active 2 smartwatch and it created a perfect coating of glass that will help protect my watch from the bumps and scrapes it gets at work. If your device already has scratches, I recommend a mild (low content) diamond paste being used first to buff out all the scratches, as it will make this product apply evenly to the entire surface. My watch now looks like it did when it was first bought, and has a far better scratch-resistant surface. The instructions are crystal clear, as well, so follow them to the letter. I would recommend this for any smart device that gets a lot of wear and tear. I would have applied it to my smartphone, as well, but it currently has no blemishes and I'm very careful with it. In hindsight, though, I'd have been better off being overcautious, as this coating is likely stronger than the material my smartphone glass is made of. Still, at the price they charge, there's no downside to purchasing a separate kit for each device you need to protect. There is no reason to hesitate. If you want an incredible, affordable scratch protector, there is no easier solution than this.
