It's hard to put them down - Great purchase
It's tempting to write this review one handed. Each Vortex is roughly the size of a quarter, and having both or even just one in your hand is perfect for fidgeting. The aluminum ones are extremely lightweight, so if you want a bit of heft to it, look at the other metals they offer. The vortexes do 'clink' so they're not totally silent but you can muffle it by keeping your thumb on it. They shipped quickly and I'm expecting to see them last a long time.
