This lil device is small and simple:
1) Place the Eezi Starter down somewhere firm.
2) Put your powerball on it, making sure the groove goes into the slot. (If you do that, the powerball sits nice and firm)
3) Place palm GENTLY ontop of the powerball and press the front of the Eezi starter down and watch it wind up!!!
Once you have the right speed, just take it off and start using the ball how you would, SIMPLE!
O.K, sure you can buy a spare string from powerball, or if your skilled enough you can start it with your thumb, but if you don't want to go through the hassle, then this is a must.
I think it's unfair that something so simple and usefull gets a bad review because people can start their powerball some other way.
Overall I give this 5*/5* and would recommend this too anyone who wants to quickly start up their powerball hassle free.
***EDIT: 06th August 2011; I still use this little starter and it works just as it did new (as long as you put new batteries in), I've uploaded a new and clearer video which I hope you will find more useful!***
