It arrived to my place all wrapped up in bubble wrap, the paint job was still immaculate and ready to install.

Black 2040 (European) 1 1/8 x 1.5 inch vs. Silver 80/20 (USA)PROs1. Great for small 3D printing projects - European standard2. It came w/ connective pieces/screws3. Extrusions are great to build light box frames fairly quickly.CONs1. It came packaged in bubble wrap but there were black scruffs/chips on the frame.

Could be slightly cheaper, but it did the job and shipping was predictable.Teeny tiniest nitpick would be the corner of one was not quite cut through, and had broken off the parent piece. Simple file for 5 seconds cleaned it up and another 10 with a fine file got it squared. If you're using these, you know how to do that.

Whether you've used these type of extrusions or not, you'll always find a use for more of them. They are so useful for so many things. These black ones are good looking, and are a nice departure from the plain anodized ones I typically get. I've built many temporary fixtures and jigs for use in woodworking with them. With a good assortment of attaching brackets and braces, you can build nearly anything you can imagine, and do it quickly. Adjustment and disassembly is a breeze, so you are ready for the next project.

This seems like the standard extrusion profile you expect. It arrived adequately packaged and without dents or dings. Sturdy stuff. Seems like its priced consistent with other sellers. The finish is high quality and very attractive. Includes a couple angle brackets as well.

I wanted to make a brace for my 3D printer's gantry. This did the trick! The only issue that I had, which was not really an issue, but was rather a challenge that I enjoyed solving, was now to attach it to the existing structure. I designed a bracket, printed it, and then am happy to have a more stable gantry for my printer. Obviously this could be used for a great many purposes. All of the appropriate hardware fit the tracks, like the nuts that go in and lock when they turn. It is always a pleasure when things work as they should!

dimensionally accurate and arrived on time.

Love for what I could do with it !
