The Ouroboros is an approach disc rated 4/3/0/3. Zero turn with a 3 fade suggests an overstable flight that resists turning over and finishes firmly left for a right-hand backhand. Its ratings suggest it is less suited to players seeking turnover approaches or a soft, straight finish. EV-7 calls it an overstable approach disc with a flat-top profile and a beadless rim built for torque resistance, and links the name to an ancient symbol representing an eternal cycle. The PDGA certified it on 1 December 2025 (25-177) under the spelling Ouro Boros, which this page also uses. TryDiscs lists it in OG Base.

1 review from 1 store

The EV-7 Ouro Boros has only 1 review so far, so one opinion can swing the picture. That's why there's no star average yet.

Try Discs adds up reviews from six disc golf stores, so you see what players think across stores, not just at one shop. Reviews are great for spotting proven, popular discs. Take the details with a grain of salt, though: runs, plastics and skill level all change how a disc flies, so your experience may vary.
