Gym Chat has a discussion threat on the “best way to get better splits/flexibility”.
It includes a link to research by Bill Sands, Jeni McNeal and others:
CONCLUSION: This study showed that vibration can be a promising means of increasing range of motion beyond that obtained with static stretching in highly trained male gymnasts.
Flexibility enhancement with vibration: Acute and …[Med Sci Sports Exerc. 2006] – PubMed Result
Jeni brings her vibration machine (video) everywhere. She’s very positive on this training method.
But where can you buy a machine?
John Wingfield from Indianapolis sells them for $1800.00 plus shipping. That includes research study resultts, the suggested protocol for use, and a 1 year parts and labor warranty.

Disclaimers: I spoke with a gymnastics coach who worked with former World Champion sprinter Donovan Bailey’s Athletics group. They tried vibration for a number of different purposes, ultimately concluding that it was not beneficial enough to use.
We made our own machine in the 1990s at Taiso Gymnastics based on the model brought to Canada by Edouard Iarov. We had mixed results, to be honest.
Though the research looks positive, you need try it with your own athletes before being convinced vibration works to improve flexibility.
