I had saved up 72 spins and got cash on all of them except like 2 of them (one where I got the 5 ec, and I think one dn or something)
100 speakers, 3 kinkis and ecs. This was when it first launched. After that, its been low cash and chibis.
I found a get better stuff from spinner when i drop cats n kini or around time i buy ec from store??maybe they increase your chance?
