Title: Low quality but functional
Review: I bought these because Geomag Pro are not sold in the US, and international shipping on them is prohibitively expensive. Compared to Geomag these are very low quality. The metal plating on some of the magnets was bubbling up, and on some it had already flaked off completely, causing black magnetic dust to accumulate. The strength of the magnets is a fraction of the strength of Geomag. I am still able to build with them, but the weaker magnets make some shapes more difficult to put together. The ends of the rods are larger in diameter, making it difficult to build some shapes that require a lot of rods to be attached to one ball. The balls are slightly larger which compensates for this problem somewhat, but not completely.For the price, I expected these to be of much higher quality. If I decide to make another purchase, I will either pay the international shipping on Geomag, or just refrain altogether. I would not get these again.
