Oh I’ve used theirs on my M3 and I love it. I liked the $20 offer but $9 gets eaten up with shipping charges. So, just wasn’t worth it. I think I’m more inclined to just keep the ridiculously shiny plastic on it until I have something in hand.IMHO, Abstract Ocean makes the best glass screen protectors. I've had the matte versions on my two 2020 MYLR's for almost 4 years and they're still perfect.
They are making a tempered glass version for the CT, but are a bit delayed on production. In the meantime, they have a PPF version that includes a $20 coupon for the tempered glass version when it's available.

I'm not affiliated with AO in any way, just a very satisfied customer. I'm still waiting for a VIN, but once I have it, I'll be ordering mine from AO.
