Good value, easy to use.
Used to build my kitchen cabinet in my van. Very light weight. I did need to add a back panel to stabilize it. The standalone frame is not meant for heavy weight. Worked great for my purposes.

Sturdy and asy to use
So sturdy and easy to use. Love that one side slides while the other is fixed.

Good, but can be hit or miss.
I like these as I have found them to be generally convenient and durable for heavy-duty use. However, I recently encountered significant quality control issues with several pieces. Of the three sets I bought, I encountered one in which several screws absolutely refused to thread all the way through the bracket. By the end of that pack, I was left with 4 brackets and no more usable screws. If it weren't for the extras that came in the other two packs, I'd be down a fifth of a set.

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.

Some may not be tapped correctly
The brackets are very sturdy for their size. I've purchased three sets of these so far. For the first two sets I'd give it 5 stars, but the latest set had a problem. Usually the screws go in very easily, but the most recent set had seven that required a lot of force to get the screw to insert all the way into the bracket. The picture is of those seven. My best guess is that they weren't tapped correctly. I may have to use them anyway, but I'm avoiding them for now. Theoretically they will still work, but they're a pain to work with.

Fantastic
I'm thoroughly impressed by how well these held up in my project. I was demanding more than their allocated weight, and they hold up no problem.

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.
