Devil stick is good for co-ordination and building hand and wrist muscles that are used for chucking
it can be hard to get the hang of it at first but once you know the basic tapping spin it becomes natural
this is the stick I have , a Mr Babache glow in the dark stick (the green one) its really grippy which is good for beginners
or if you want to wreck your wrists from falling like I have done many times over the years then I'd reccomend getting a skateboard
I know its not a juggling/freestyle/thingy but its a cool hobby
