Fenzy's are increasingly hard to find. This one completely works, and has been taken apart and serviced. It operates, and does not leak. It comes with the BCD and the bottle. I've shown the bottle in both pictures, but there is only 1 bottle. This guy dives, and I have been diving it.
100 bucks plus shipping. All the ones you can find are in France, and they are at least 100 bucks with the exchange rate and international shipping.
