Good quality and large size
This cradle is nice but was to big for my small desk space. The base is solid but to my suprise the strings were thin and plastic however, If your looking for a large size cradle this is it.

Looks nice, not best quality, good value
This isn't the best quality but for the price I am still extremely happy. Balls are shiny, it works okay, and it looks fantastic. But the Plastic wire suppending the balls were bent straight from opening the box, the plastic can not straightened from what I have tried. as you can see in the picture, one ball is fairly misalligned and can cause the balls to wobble. The length of the wire on both sides of the ball look good but one side is always a bit more tight then the other and can cause wobble (break cycle pattern and diverge into chaotic motions).

Garbage, not at all what I expected based on the older ones I remember
DON'T buy this if you want to get it as a gift...it's a really low budget version, poor quality. I'm writing this review kinda late because i finally just threw it in the trash a minute ago and I'm buying a better one. It's super light, dental-floss like string, the balls are not even heavy enough to actually reproduce the action you're expecting (the whole thing swings and the transfer of power isn't 100% because everything is just too light). So annoyed I finally just threw it out...grr

Initially the motion didn't last long but once the weight of the balls had pulled the kinks out of the lines it worked just fine. That didn't take long. My son loves it.
