Worth the money
I’m really impressed with these BLCCLOY Aluminum Extrusion Corner Brackets. They have a nice, solid weight to them, and the black finish looks much cleaner than the standard silver ones you usually see. I used them for a custom frame project, and they lined up perfectly with the 20 series profiles without any awkward gaps. The set screws hold tight, and honestly, for a pack of eight, the value is hard to beat. If you're looking to stiffen up a 3D printer frame or a small rig, these do the job exactly how you'd hope.

Simple As
They feel solid enough as the end pieces for my Pc frame, the grub screws are not pointy, they have an inverted point that makes a circular dent in the extrusion. Tighten it down enough, and it feels secure.

Great price for 8 and all great quality
Still working on the enclosure I'm building with these...will post a pic if I remember. They look really nice on what I've got together so far. No issues with any of them, everything seems milled perfectly.

don't fit flush, powder coat ruins dimensions, seem to have shrunk in casting. I advise against.
I had to use a hammer to get them to fit. the first millimeter fit but after that, the rounding and expansion from the coating made it impossible to insert further. some choice taps with a hammer worked, but I'm using standard misumi T-slots, which I have confirmed to be dimensionally accurate. These things don't even sit flush with the bottoms of attached extrusions, and every part of it is rounded and bulgy. generally suboptimal parts in most ways. They seem strong, but definitely are stressed by how I had to hammer them in, and they seem about 2% smaller than they should be in every way, as if someone used an accurately sized one to make a mold, so metal shrinkage caused the parts to be poorly sized.
