for Fiio M11 Plus LTD Tempered Glass, 9H Premium Scratch-Proof Protective Tempered Glass Screen Protector for Fiio M11 Plus LTD 5.5inch MP3 Player (Front and back glass)

Worth the price.

This is a great tempered glass screen protector. It fits the 5.5" screen of the Fiio M11 Plus from edge to edge perfectly. Full screen adhesive that is easy to install and bubble free. Fair warning to Fiio M15S owners, while the 5.5" screen size is the same as the M11 Plus, it is not designed for the M15S and will not work. Installing on the M15S will result in an approximate 1/4" area around the perimeter of the screen where the adhesive won't stick. Also, the M15S will not fit in the leather case with the protector installed.

Ordered this because the factory-installed glass screen protector was a fingerprint magnet, nothing the least bit oleophobic. Nice manufacturing touch to include, but couldn’t stand the constant smudges. This does the trick and is easy to install. Pro Tip: Buy the front & back kit, install one on the front, keep the “back” (identical, insofar as I can tell) as a backup. I keep mine in the original-equipment leather case, so I don’t need protection on the back. Good stuff, good buy.

So I use the Fiio M11 Plus in my car as a coax source direct to a DSP. I recently used a scosche universal magnetic mount kit and the FIIO fell off my dash and hit the seat rail. the FIIO is too heavy for this magnetic mount :( I instant saw the screen SHATTERED, thinking the worst I peeled back the tempered glass and it was perfect underneath! I instantly ordered a pair of these and will be keeping them on the FIIO as added protection. TOTALLY WORTH IT, even if you're just putting it on the back.

Was given a used one. The seller did not have the courtesy to reset the device and instead sent it to me with the previous owner's credentials still logged into. For the price, I expect a new device.

the product came with scratch marks

Just don't waste your money.
