New MacBook Air M3 15” user!

Hello! This is my third MacBook the first was the 2016 pro model the second a M1 air 8/256 13”, this one is 16/512 15” and I love it! I use a cover in the others, but I hear that is not good in M2,M3 models.

I bought a soonjet cover but im not sure if I should return it or keep it, I don’t want to damage my Mac (that’s why I bought the case lol).

What u ppl think?

Is a big no? Or should I use it?
