This is my wife's primary regulator and I dive with it occassionally as well. Between the two of us, we probably have almost 200 dives on it.
If you are searching for a mid-priced regulator that mimics the performance of ultra-premium regulators - this is it. My primary regulator is a Legend and I can barely tell the difference between the two underwater.
The only minor drawback to our (previous version) of this regulator was the radial hose routing required a bit more packing space for travel. But that issue has clearly been addressed with the new first stage design.
I would also recommend upgrading to the "cold water" version of this regulator. Doing this provides peace of mind that you can dive this regulator in a wider variety of environments.
So if you're looking for a mid-line regulator that mimics the performance of premium regulators, this is it...
