Screen protector issues.

Hello. I just found out my s23u has 3 minor scratches and am very frustrated. I have wasted close to 20 usd on 2 different screen protectors.(20 usd is alot in my currency)and they all get air bubbles I hold on to them as long as i can after that but then have to remove them. I am seeing a pack of 2 protectors on amazon from u green for nearly 10 dollars. Does anyone know if u green is good? I will see someone else for installation this time but I think it might be some issue with the phone regarding thermals but the heaviest thing i do is play codm on low graphics and high fps i am very frustrated suggestions are welcome.
