Instructors who have dived with this regulator claim that it works extremely well in any condition. The only drawback is the relatively big and heavy first stage.

Scuba Lab has given this regulator a perfect “20 out of 20″ score.

The price in more retail stores is more than 500$. However, I have seen one being sold on ebay for as little as 305$ - a real bargain!
