AmFilm works well. Under $10, no complaints after a year of daily use.

Skip tempered glass, honestly. Had issues with those lifting on curved screens. Look into a TPU (Thermoplastic Polyurethane) film protector instead. More flexible, better adhesion, and self-healing properties. They're thinner, so less impact protection, but much better touch sensitivity. Worth checking out before committing to glass; I use Spigen on my dashcam screen.

Hey! For under $20, tempered glass is your best bet. I wouldn't overspend on brands; even generic ones offer decent scratch protection. Just make sure it's properly aligned during application to avoid bubbles - that's where a lot of protectors fail. Check reviews for ease of install; a badly applied protector is a waste of money, right?

Heads up on cheap protectors: some can shatter into tiny, sharp pieces on impact. I've seen it happen. For safety, consider a tempered glass one, even if it stretches the budget a bit. Spigen's a decent brand; look for one specifically designed to minimize splintering. Peace of mind is worth a few extra bucks, trust me.

Been using LK protectors for years; they're cheap (~$10) and work. I've learned that even cheap ones prevent major scratches over time. Just replace 'em annually.

Lots of generic brands flood the market, making it tough to pick. I'd suggest researching Tempered Glass brands. Are they REALLY tempered? Under $20, quality varies wildly.

Skip the pros! Amazon has cheap film protectors. Apply yourself, save $15. Works well!
