for Apple Watch 42mm Series 3/2/1 Smartwatch Screen Protector, Max Coverage Bubble-Free Anti-Scratch 3D Curved Tempered Glass Film [9H Hardness+Crystal Clear+Scratch Resist+No-Bubble](42mm-2 Pack)

Don't waste your money, I have used several glass screen protectors and they have saved my watch. But his brand is the worst I have yet work with. Sizing is wrong ans can not get bubbles out. Go with another brand and spare yourself the grief.

Tried both, could not prevent bubbles during installation. First time only In one corner, so I tried a different protector. This time I had 4 bubbles. I could get them to disappear, but they came back within a few seconds. Seems like a good durable product, but just could not get it to install perfectly.

I ordered these for a series 3 42mm watch, and they are slightly wrong in size for the the face. As a result, even after getting good adhesion with no bubble initially, it keeps separating from the watch. Don't waste your money on these.

I installed two of these on two different Apple watches. They both cracked the next day with normal use.I was not able to get all the air bubbles out from under the protector.But I was more interested in protecting the screen of the Apple Watch.I would not order this product or refer it to anyone.Just my opinion.

The package comes with 2 screen protectors and I just left the second one on until I buy something else. It is so hard to make sure that the alignment is correct and you will only find out when there are giant air bubbles covering one side of the screen. I tried removing to place it correctly again and made it even worse.

The first screen failed to go on. The second screen lasted about a week.

The first piece broke while I was trying to get the bubbles out of it and the second one wasn’t sealed completely and got water logged. Good thing I have the waterproof watch or I’d be screwed. The air bubbles are impossible to get out and make an easy seal even with the alignment stickers. Wasted both covers

This thing was awful and I was not able to use it. The sticky part was not covered well
