Mr.Shield Screen Protector Compatible with OnePlus Open [Front Screen ONLY] [Shorter Fit For Case Version] [Tempered Glass] [3-PACK] [Japan Glass with 9H Hardness]

I thought it was too narrow at first, it just barely goes to the sides of the screen. You have to align it PERFECTLY or you'll have a sliver of screen showing on the side. Once I put my aramid case on I realized the protector is practically the exact size of the cutout. Any wider and it wouldnt fit right. I love that there is no camera hole, makes it looks way better IMO

This case turned out to be better than my expectations. The gray textured case does not leave finger prints or anything. Does not peel off my screen protector and it’s sturdy at the edges too. Buying it again.

This is finally the one. This glass has a better oleophobic coating and is more transparent than all of the other tempered glasses out for this phone. The OnePlus open original case also fits!!! I've been waiting so long. The only downside I can see is you have to align it properly otherwise the sides won't fit the actual display area. It's like an exact fit for the display size not the actual full screen.

This screen protector is basically the exact size of the front OLED screen (not the whole glass) on the OP Open, so without a case it would look like it's too small. The easiest way to apply it is to put the OEM case on first, then just set it in against the left edge of the case frame. It also fits well inside the Nillkin case. High quality protector, WAY better than any case with the screen protector built in. Nice smooth touch and rounded edges.

This screen protector is too small. Here is the one from OnePlus on the one I received. Please note that this also doesn't have any hole for the camera which isn't an issue just wanted to also call it out.

Easy install. Holding up great with the factory case!

This is a very good quality set of screen protectors, with good instructions and accessories that help with cleaning and installing. However, the screen protectors are sized to fit within the borders of the case that frames the front screen, and these screen protectors are not size compatible with my case. I have the Spigen Thin Fit Designed for OnePlus Open case (sold here on Amazon), and the screen protectors are about 0.3mm too tall. I tried the very good method mentioned in another review of keeping the case on so it acts as a guide to center the screen protector within the edges of the case, but the screen protector is very slightly too tall, and although it can be pressed past the top and bottom edges of the case, the case puts pressure on the edge of the screen protector, and causes it to bubble up at the top and bottom of the screen. Removing the case afterward allows the screen protector to settle back down flush, but putting the case back on again causes just enough pressure on the top and bottom edges of the screen protector to lift it. After wasting 2 screen protectors, I gave up and decided not to use any. I'm pretty pessimistic I'll ever find one that works well, since I have a drawer full of glass and plastic ones of different brands, and all have problems. The glass ones don't fit well with a case. The plastic ones attract so much dust (static cling) that my screen looks like $#!%.

It does the job.

As others have posted, this screen protector is the perfect size as it is the only once I've found to be case! Unfortunately, two of the corners won't lay down flat - and so, I have rather large bubbles in those corners (which disappear when I press down on those areas, but then lift again when I release). Bummer as I had high hopes. I've only tried one of the three in the pack - so can't comment on the other two.

I was annoyed to discover that the screen protector did not cover all the front screen. It is at least 3mm short across the phone and top to bottom. It also started separating from the phone screen a couple of weeks after installation.
