Fantastic purchase

I pre-ordered my pair back in spring, and when they arrived they still somehow exceeded my expectations. The quality is incredible! Aside from the obvious convenience of the magnetic collar system, there are many other reasons to want these.

The machining all around is flawless. I expected at least tiny imperfections somewhere, but there's nothing, not even a tiny one. By far the highest quality machining I've seen from a product so far.

My favorite part of these is actually the knurling. It is slightly passive I would say, and feels great in the hand. If you've ever held a barbell or dumbbell with low quality knurling, you'll know how big of a difference it can make.

The one criticism I have is probably the same one many people have, and that is that there's always going to be some slack between the collars and plates. It isn't a big deal, which is why I'm still more than happy to give this 5 stars, but it's noticeable, so it may turn some off of this product. Perhaps Gungnir may decide to put out their own machined weights that would fit perfectly, but until then it's going to be something you accept when you buy these.

Thanks Andreas, you told me the quality would be fantastic, but you undersold it. These are so great!
