I have the stand as well, I noticed that when used with iPad Pro M1 the edge is not aligned perfectly, however it aligned much better with iPad Pro 3rd gen. I really like the weighted base, because of this I use this setup more than my MacBook Air. Mostly I put it on my lap. It’s a great stand but little pricy, I got it from Moment for $50 it’s a no brainer! I’ve been thinking about getting the M4 13” Pro but I’m not sure if it’s gonna fit the stand. That’s how I landed here 🙂
