Review on 🔌 6 Packs of CENOZOIC L Shape 4-Pin RGB LED Connectors: 10mm Wide Right Angle Corner Solderless Adapter Terminal Extension for 5050 SMD RGB LED Light Strips by Noel Schmits

You've got six of these, they work great! They serve their purpose, they are 5 stars! However, they are usually used when working with projection screens. As you may know, the distance between one cut and another in LED strips can vary. I just tested/installed LED strips with 6.5" spacing between spots that can be cut. So you can start cutting and joining a corner, but the chances that the cut will be exactly where you need it for the next corner are very slim. It's not the end of the world, you can manipulate, bend, twist these strips, but you may end up with a lighter corner than others because you stacked and stacked the lights. I think I was only able to use 1 corner adapter in the end. Either way, this is food for thought. I've included a few images to show you what a good corner looks like with a corner adapter and what a corner might look like without. Therefore, for projection screen installers, I would buy LED strips with a shorter cutting distance. The math might still not work for you, but at least you have a better chance. This version of JoFly has a cutting distance of 4 inches: https://www.amazon.com/gp/product/B08ZCSNKNKC.
