I used these rods in a 3D planetarium assembly and they worked great. It was important that they are straight as an arrow and have the same diameter of 5 mm so that the model works perfectly. I bought other "5mm" rods from a hobby store a few weeks ago and they were closer to 5.5mm and would have required major modifications to many parts of the model. If you want accuracy, buy it.
