FiTSTILL [9 PCS] Tempered Glass Screen Protector Film for DJI OSMO Action 4 Camera+3PCS Front and Back Screen Protector+3PCS Lens Film Foil+3PCS L...

In the end, the protectors do their job and protect the camera screens. However, there are issues outside of the quality of the protectors themselves. The instructions are terrible, with incredibly bad English. It's a shame they don't get an English-speaking person to translate correctly. The wet wipes included in the package for cleaning your screen are terrible. First of all, they are already dried out so really can't be called wet wipes. Second, they are probably the smallest wet wipes I have evr seen. I have seen bigger postage stamps! Basically useless so use your won wet wipes. Most protectors I have used in the past have some sort of guide system to align with the screen. Nothing of the sort here so you just need to align manually. Luckily these are small screens so it isn't very difficult. I always have a ND filter on my lens so I did not use the lens protector. I did use the protectors for both the front and back touch screens. They both applied nicely without any air bubbles and adhered pretty well. Touch sensitivity seems to be just a bit less than without the protectors but overall quite usable. So, yes they do work, but the entire package could be better.

Action cameras get knocked around a bunch, can be thrown in a gear bag, and I wanted to make sure that I didn't get scratches all over the front and back screens of my new DJI Action 4 camera. Overall, I'm pleased with this kit, but I did have a few issues to be aware of. The kit comes in a nice little plastic case and it has three sets of everything you need to install the tempered glass protectors. There were 3 microfiber cloths, 3 sets of wet/dry wipes, 3 each of back/front/lens glass protectors, and 3 sticker sets to use to remove dust from the screen and align the glass to the install location so that when you pull off the protective film you can flip the screen protector right into place without it being off center. If you have done this process before for your phone, this is the same except much easier since the screens are so small and you aren't trying to line up notches around cameras in the screen. The issues I experienced are: 1) The wet/dry wipe package of the 3 that I opened had a wet wipe which was completely dry. Not a big issue for me, since my action camera screen was still clean having just come out of the box. 2) The first rear screen protector I opened up had a manufacturing defect of a bump on the corner/edge of the side which would touch the camera's screen, and so it would not lie completely flat on the screen (it was hard and I could not scrape it off with my finger, so it was not dust). The next rear screen protector was fine, and installed easily. The documentation with the kit states that there's a "LIFE-TIME WARRANTY, we will ship you a new one if any problems...Please feel free to email us", but no email address was listed on the card. I was able to register my purchase on the FitStill website and use their customer service chatbot to record the issue I was having to see if they would be able to send me a replacement rear glass protector for the defective one, and the chatbot reported I would receive an email response about next steps within 24hrs, but after three business days I haven't received a response (and have checked junk/spam). I haven't had/used the protectors for long enough to be able to judge the long-term adhesion capabilities, but it's nice knowing that I still have at least 1.5 sets in case I scratch or lose one of the protectors (adhesion issues are probably higher risk with watersports). I chose not to put the lens protector on the camera lens because there is already a removable glass lens cover and I didn't want to put another layer which might cause reflections or reduction in quality, when I can replace the lens cover itself if there was ever an issue. I saw another kit which was similar to this which included a silicone lens cap, for a few dollars more, and it would have been nice if they had included something like this in the kit, but it's also nice to have a choice of spending more for the lens cap or less if you don't need it (I've 3d-printed caps for other action cameras in the past since they are even cheaper and it doesn't matter that much if I lose them since I can print another.) 1-star removed for the manufacturing defect and response time exceeded the promised time, but overall it seems like it will do a good job after installing the protectors and confirming that they stay adhered without bubbling after a few days of use.

This set of Osmo 4 works great for me so far. They dont seem be lessen the clarity of the video nor do they make the touch screen less sensitive. Putting these on was very easy and I didnt have to do anything squeegee of trapped bubbles since these screen protectors has some stiffness to it. You wil have to make sure that your screens and lens are free and clear of any dust. I use tape to lift any small dust particles before laying down these protectors. Highly recommended.

Don't waste your money. The return period is 30 days, and chances are you won't change the screen protector 3x in 30 days. I put one on my DJI asmo action 4, and the screen protector cracked within 3 days, and I wasn't doing anything remotely extreme. The second one cracked taking it out of the little foam envelope, and the third one had "stuff" on it, as if it had been used. The packaging states lifetime warranty, email is if any issues, but doesn't provide an email address

Never experience throwing it to test the protection glass into my dji osmo action but overall the stickeness, thickness is right as what the description said.
