Review: Buy these and not the other ones! - These corner brackets are amazing and we'll constructed. Quality control is outstanding, with the other brands I'd have a few that weren't useable due to the machined holes not being cut properly.

### ⭐⭐⭐⭐⭐ These are the good ones!
*by M***G on August 20, 2022*

Super strong, nice 6mm bolts, easy to thread every time. These are the best 90 deg fitting that I have found. I'll use these and only these. These are the good ones for any 2020 project.

### ⭐⭐⭐⭐⭐ Buy these and not the other ones!
*by B***. on April 4, 2022*

These corner brackets are amazing and we'll constructed. Quality control is outstanding, with the other brands I'd have a few that weren't useable due to the machined holes not being cut properly. I like that the thickness of the bracket matches the 2020 profile perfectly

### ⭐⭐⭐⭐ works OK, bracket slots feel a bit oversize for M5
*by A***R on April 7, 2021*

Fits my 2020 extrusion OK and holds securely. The provided bolts are M5 and their thread OD is around 4.9 mm, but the oblong holes/slots in the angle brackets measure 6.2 mm across. That's even a bit more than the width of the T-slot in the extrusion (6.15 mm in my case). So this bracket could easily accept M6 also, and the M5 seems a little sloppy to use with this much slot width, but anyway their bolt heads are large enough (9.4 mm OD) and it does work.
