Have used these before so when I damaged my last one I ordered another set. I badly scratched and cracked the last 2 , but they held up and protected the watch. Not a trace of damage to my watch, just the protective shields. I am a cluts, I bang into everything, catch the edge of my watch on stupid stuff. do the same with my rings but they are all metal.these shields really protect the watch.

The glass screen protector protects my $200 Fitbit Blaze from accidental scratches. The protector went on easily. I had no issues with dust or bubbles. I don't believe I have actually tested the glass, but I sure feel better about protecting this expensive device for just a few dollars.

I just want to make it clear that this screen protector does what it says it does. It's easy to apply, it's crystal clear, and does not hinder the responsiveness of the touchscreen. However, I gave it 3 stars because I can no longer close the Blaze inside its charger. The design of the charger seems to have zero tolerance for extra thickness, especially the thickness of this glass protector. But because I like this screen protector so much, I'm going to buy a different charger that won't require me to pop out the Blaze to put into a housing just to charge the darn battery. If that doesn't work out in the long run, then I will just have to buy a plastic screen protector that won't drastically change the dimensions of the Blaze.

Update 12-08-17: I bought the 3rd party charger where you don't have to pop the Blaze out in order to charge the battery and it's great! I opened another one of the screen protector and installed it on my Blaze again. Unfortunately, this second one is nicked at the top. It doesn't feel like it would scratch me badly if I accidentally brush over it. Oh, well, maybe 3rd time's the charm!

I gave this product a 5 out 5 starts. It does what it is intended for. It matches my Fit Bit Blaze perfectly. You can't even tell it is on. Crystal clear.I did not put it on myself though. I usually take my products to a cell phone accessories store where the owner has experience applying screen protectors.

When it sticks, it is good. It just seems like it is a drop short of enough adhesive. First cover didn't go 2 weeks. Second has stayed on longer, but one corner isn't secure. If I could find a good adhesive to use, I would add it onto the back to give it the protection needed.
