MakerBeam 300x10x10mm Beam Black anodised (Pack of 4)

I received these today, along with some corner brackets, and within an hour of opening the package the frame I was building was finished.Would scraps of wood and some brackets from the hardware store have been cheaper? Yes, but these are much more precise, which I needed for my current project.Overall, a solid product, if slightly pricey. Still, I would recommend these to anyone.

I bought these to build a structure for a robotics project and they worked out great. I plan on using them in future projects. The beams are solidly made and had no warping or bends. They are also center drilled all the way through and tapped at both ends to receive M3 size screws. If you have used aluminum extrusions before but need to build a smaller structure, then I would highly recommend this product.

The product is good quality. Honestly I did not look closely at the measurements before I purchased them. These are not a size I can use, they are much too small. However, they are exactly as described.

Works great if you need a mini t bar slot. Be sure you know that this is smaller than the 1" extrusions we commonly see.

Pretty good and sturdy. Problem is, it is too expensive and no other sources of accessories other than makerbeam themselves. I guess only the M3 Nut is available elsewhere. So if you run out of screws or of attachments, only makerbeam can help... for a price.
