Review on 🏢 Simpson STB2 50334 - Enhanced Durability for Cracked and Uncracked Concrete by Justin Hollins

I used these to hold deck bolts in place. The only complaint I have is the actual size of the shield. Seriously, not enough on distribution. If you can drill straight down without the slightest bit drift or tilt, then you're good to go. Once you've inserted the anchor and started tightening, you'll find that the slight itching you now have is causing the entire screw (not just the anchor) to turn. Generally DO NOT RECORD! And now all the other holes you drilled should be re-drilled.
