Review: Exactly as described. - These are nice quality and make a perfect 90 degree internal mounting bracket on 2020 extrusion. These seem sturdy enough for most applications of 2020 extrusion.
Review: Helped square the machine for smoother motion - I bought these for the Ender 5 I own. It's still in pieces at the moment but these corner brackets work exactly as specified. They helped me make the entire printer more square than before my tinkering. The Y axis motion is smoother due to being more square. Absolutely a breeze to use. They sit inside the frame, so they are not unsightly like the original corner brackets. Remember to use thread lock on the grub screws.
