tbh you dont need to spend a ton of money on those super expensive boutique brands. Most tempered glass protectors are basically the same quality as long as they have 9H hardness. I always look for a multi-pack, like a 2-pack or 3-pack, because if you mess up the alignment the first time (and we all do lol) you have a backup ready to go. Spigen Glas.tR EZ Fit is usually my go-to for value because they include a plastic frame that makes it super easy to line up. Pro tip for installation: do it in the bathroom after running a hot shower for a few mins. The steam knocks all the dust out of the air so you wont get those annoying tiny bubbles underneath. Also, make sure the screen is 100% clean with an alcohol wipe before you drop the glass. Honestly, the cheaper tempered glass options protect just as well against scratches as the $40 ones, so dont overthink it too much. Just make sure its definitely glass and not the old-school plastic film stuff which scratches way too easily and feels weird to the touch.
