9H Hardness Premium Scratch-Proof Protective Screen Protector Tempered Glass Film for HiBy Digital M300 HiFi Music Player (2pcs)

The most common question about this product is: why would you want one, when your smartphone does all it can do and more? For me, it's because I want a compact Bluetooth music player that I can take to the gym and not worry about losing or damaging my phone. The M300 gave me a lot more than I thought I was buying. As a fully functional Android, I downloaded and used some apps, including those to control my earbuds. As others have noted, the M300 has no cellular or camera capabilities, which I don't need in the gym. Room for improvement? Simple set-up instructions would help, or even a note saying that information could be found on the product website.

Seems like such a simple thing but this is a great protector. Fits absolutely perfectly, comes with a little prep kit to make installation easy, seems thicker and heavier than a lot of similar products, and it came packaged very nicely with lots of protection. Basically just a great product!

Be nice if there was a template to line the glass. Now I need to order another one. 😒

I usually don't like using screen protectors because I can never get them to adhere right. But I wanted a glass one to protect the soft screen on my Hiby DAP. This one went on so perfectly that you can't even tell that it's there. Feels nicer than the Hiby's soft screen. They even included little alcohol wipes to clean the oils off your device prior to putting it on, which is a very nice touch.

These are a tricky bunch to put on and that is 100% the M300's fault, not this product. There is barely a lip to trap this screen protector in for alignment purposes. took three attempts to get it on, and still got crap stuck under it, again, not this product's fault. But it's a perfect fit, with maybe a hair's gap of wiggle room.

Price is great. Fits perfectly on the m300 used it for couple of months now and still doing great hasn't scratched yet. Quality good

The screen protector fits the M300's screen well, but it does not appear to have "round beveled edges" as the box says. Because the edges are very thin, rough cut, and not rounded, they are quite fragile in the corners.

Not impressed. I can’t get the thing ti lay down correctly. Air bubbles, dust. I hate these things.
