Tibet Tech solar prayer wheels rotate all by themselves with solar power. We have seven Tibet Tech solar prayer wheels that have 1-DVD, each with different benefits and powers.
We also have the Tibet Tech 8-DVD solar prayer wheel, the most powerful prayer wheel in the world, which has eight blessed and consecrated Tibetan Buddhist prayers.
Note: The DVDs are not designed to be played with a CD/DVD player or computer. The power of the prayer wheel comes from one's spiritual intention and the blessed and consecrated DVD.
