Worthless Junk
Do not waste your money on this product. Is very poorly and cheap made. The Styrofoam was damaged and loose. And all the steel balls were wrapped around each other. It’s impossible to untangle. I was looking forward to get this and I’m very disappointed. Total junk if I could give it less than one star I would. Thanks.

Grandson loves it
My 9 year old Grandson adores this and can sit and play with it for a long time. It seems to be made fairly well.
Satisfied –
Nice cradle. Lightweight base.
Works but is lightweight. Should have purchased a heavier base. If you take two balls and release, then two ball will be displaced at the end. Very fun toy for kids if all ages ( it was for my husband)
