I've seen a few stomach-churning pictures of Pocket 3's with scratched and cracked screens and it's a traumatic experience. At a current price of under six pounds for three sets of screen and lens protectors it seems silly not to pop one on and hope that when the unthinkable happens they can make the difference between disaster and your beloved camera living to film another day. I have several K&F Concept items which I use with my Sony RX10 III so I wasn't too worried about quality. Inside there ais a large(ish) orange packet with a mediocre microfiber cloth crammed in. There are also three brown card envelopes inside each of which is a 9H tempered glass protector for the screen and one for lens along with a small sheet of stickers for alignment and dust removal. Task one is trying to get the stickers off the sheet without bringing the backing with it. It seems the machine that made these was to cut a smidge too deep making getting the stickers off a right pain. Once you've cleaned your screen and lens and removed the dust you need to fit the protectors. There's no protective sheet on top so it's just a case of removing the back proctor using the pull tab. Next you line them up and press and if all has gone well, watch the dark shadow creep to every corner as the silicone adhesive does its thing. I made that sound easy but there's every likelihood you'll need to lift the glass at least once to get a perfect alignment because these things fit right to the very edges. The lens protector in particular is an almost precision fit but the lens has a very slight recess which helps enormously. I didn't see or feel the lens protector bedding down which was a bit concerning but it's still on so fingers crossed. I did seem to get a single speck of dust under the screen protector which left a bit of a bullseye as you can see from my photos. I think I can live with it so for now I'm not going to try again. The lens glass went on first time which was a relief considering how small and fiddly it is, and how large and awkward my fingers are.The lend protector does have a small mark on it which is fortunately near the edge so again I'll live with it. At first, I thought it was a protective top layer but it isn't.I'm not blown away by the quality. The stickers are useless, the cleaning cloth is poor and there was a mark on the lens glass but at the price, and considering the money they may potentially save me, I'll forgive a little. Certainly worth the money on balance.
