L K [6 Pack] Screen Protector for Apple Watch Series 4 40mm, [Full Coverage] [Self Healing] Anti-Bubble for iWatch Flexible TPU HD Clear Film, Lifetime Replacement Warranty

So easy to adhere! Stays put and protects my watch.

For starters, I watched the installation video before even starting. Then I followed the video step by step, with somewhat mixed results: The rings are very helpful, which keep the Apple Watch in place during installation. Although I did notice some stickum on the back of my mother’s Apple Watch after installation. So I used the included alcohol pad to clean it, then dried it with the (also included) dust cloth. As for the installation itself, unfortunately on my first try, the #2 tab actually separated from the piece it’s supposed to lift off, so I had to abandon that screen protector and start over. Also as one previous reviewer had pointed out, there can be a line right in the middle of the screen protector once installed, the line where the #2 and #3 peel-off pieces meet. Consequently I had to remove the second screen protector and install a third one – when I managed to get rid of the aforementioned line by lifting the part under the (already removed) #2, while using the squeegee to remove #3. SO... I ended up using 3 screen protectors to get 1 good installation. Then I proceeded to install on my mother’s brand-new Series 5 AW. And having learned the lessons from installing on my own Series 4, you’d think I’d get it on first try. Alas no such luck. I also ended up using all 3 of the remaining protectors, before getting an acceptable result. (I even used a magnifying lamp this time!) Even then there are still tiny air bubbles once installed – which my Lasik eyes can see, but which I really don't think would make much if any difference to my elderly mother! UPDATE 22 February 2020: The screen protector started falling off my AW all by itself last night, even though I haven’t done anything ‘unusual’ with my AW – no swimming, no taking a shower, not scraping it against anything... I used the Apple Pay on my AW three times last night, and by the 3rd time the screen protector curled up in one corner and is now totally unusable. (Please see photo) Since I had already used up all 6 protectors for 2 AWs, I’ll have to look for an alternative. I just hope my mother’s brand-new AW is still protected – which I gave her as a surprise present only 2 days ago!!!

These work really well while they are on but don't last. I'd say I have to put a new one on every month as they start lifting at the corner and almost start sliding off. For the price I'm fine with that as it gives good protection when it's on.

Update after 6 months: this product is great and is truly self healing. I let my 9 year son wear my watch and he banged the watch face on something which created an air bubble. After a few rubs over the bubble with my finger it looked good as new. I added a before and after photo to show what it looks like right after you put on the screen protector. It will take 1 day to even a full week for all the air bubbles to go away. Once the bubbles are gone, it looks fantastic. Update: after 3 days all of the bubbles completely went away, even the small one that I circled in the photo is gone. ————————- I bought this product after having a terrible experience with the screen protectors that require a spray. The spray one just did not work for me and the edges kept coming up. I returned that one and came across this item. Make sure to watch the video to help with installation, the sticky foam holder really does help. The first one I installed following the exact instructions from the video and there were tons of bubbles and a line across the middle. I was so bummed and assumed that I did something wrong so I took it off and put on a second screen protector. The second time around, I did not bother following their instructions exactly. I just took off all the layers and placed it directly onto the watch screen (I do this with phone screen protectors all the time). It had the same result, bubbles all over and a line! I figured the product was defective and bad but because I had no other screen protection I decided to leave it on until I could find a new one to purchase. The next morning I put on my watch and noticed that 90% of the bubbles were gone! The instructions fail to highlight a key point: LEAVE THE SCREEN PROTECTOR ON OVERNIGHT OR LONGER to allow for the bubbles and line to disappear. Mine all went away on its own. Right now there is only one small bubble in the corner which I believe should go away on it's own in another couple of days. The reason why I’m giving this item 4 stars instead of 5 is because not all of the screen is protected. It covers less than the spray one. If only they could re-evaluate their product measurements so that it could provide true edge to edge coverage then this would be 5 stars.

Good
