Thanks for making the review, Luke! Super happy to be your favourite ball-maker! As to washing them in a washing machine, it is possible, more here: www.jugglequip.com/post/how-to-take-care-of-infinities And one little correction: to create the exact size-weight-squishiness combo, we just use two different plastic pellets most of the time (one light, one heavy). Only for the extra heavy balls we use iron. More here: www.jugglequip.com/post/infinities-custom-a-complete-guide
I love my Infinities. Use them since about two years and they are still in a very very good condition. By far the best balls I have ever owned. Are you going to participate at the EJC next month? I would love to buy some of the new series.
