Zshion(2 Pack) Screen Protector Compatible with PRW-3500/PRW-3100/PRW-3000/PRW-2500,9H Hardness Tempered Glass Screen Protector with Anti-Fingerprint Bubble-Free Crystal Clear

The size is just perfect for PRW-3500. No air under it. A+++++

I glad that I purchase this protection for a watch.. If you regularly work with tools, this a good insurance to protect screen, not only from scratches, but for good bang as well. It holds its self pretty good and is very clear. On the one note, its slightly smaller than the screen, so you got one shot to set it right in the center, or two (there are two in the box). But if not centered right, it doesn't look that evident or bad. It's tested! I've been in the sun long hours, in the water, diving, in walking-in coolers working and still holding.

2nd Update : Jan 22-2021I have had this screen protector for almost a year now, and the watch has had facetime with lots of sun, and mild-moderate water exposure.The screen protector has stood its ground.Thanks you._______________________________________________________________________________________________________1rst ReviewPros :1. Good fit for the Casio PRW-3500, screen protector diameter of 3 cm(atleast thats what I got).2. you get a 2 pack.3. cost effective.Cons.1. Terrible instructions :2. unless you have experience putting screen protectors and how to hand them, you might have a difficult time if you struggle with micro-maneuvers, which means you have to get it close to a good fit.All in all, you get 2 protectors, and should be able to experiment with one, and use the second one for a more cleaner "finish".Thanks for reading.

Fits perfectly on my ProTrek PRG6001CR . I have bought this brand of lens protection for all of my Casios and have been more than satisfied with everyone of them. Why pay extra for a Sapphire lens when you can have the same satisfaction with this product on a mineral crystal at a fraction of the cost. It a no-brainer .

Easy to install - seems like it will do the job - only time will tell :)

The (Zshion Casio PRW-3500/PRW-3100/PRW-3000/PRW-2500 Screen Protector,9H Hardness)were TOO SMALL in DIAMETER and did NOT cover completely.I do NOT know how to get it off to replace it.

I bought this for my prw 3510 Casio protrek. The size is a 9.8/10. The only person who knows where the silver lining will be the wearer of the watch.The tempered glass stuck immediately with absolutely no bubbles and would not budge once set.I cannot tell the glass is even there which is a plus. I took a very sharp hunting knife to the "spare" glass and did some testing.1: scratch resistant 9/10. Will not leave scratches inbeded into the glass but you can tell something swiped it even after wiping it off. Again you'll have to know where it happened to know it's there.2. Crack/shock resistance: bevel side blade, took a couple good hits(like cracking a hard boiled egg) before giving way 7/10. Don't mistreat/drop the watch too many times.2b: pointy tip of blade 0/10. This glass will not survive a head on collision with something such as a jagged rock,nail,knife.2c. Spider webs everywhere the moment it is broken. 0/10 For two scratch resistant glass protectors the money is fine. Why this product is getting a low star count is because it was advertised INCORRECTLY. A rating 9 on the hardness scale is not to be used lightly. This does not compare by any means to saphire glass which is rated a 9. I'd ask the seller to please remove such labels but it's also on the actual package so oh well. Would I recommend this? Sure, just don't have high expectations about what this glass will do for you. Scratch resistant only.

Fits the Casio Protrek as well as a Garmin Instinct perfectly. Slightly better fit on Garmin Instinct actually. Goes on just like a phone screen protector, no bubbles.
