I have used one of these (really, it's a semi-dry) a few times and it was GREAT for winter diving here in AZ (chilly, fresh water in the mid- to upper 50s) A bunch of the instructors and DMs I dive with use the same suit. They are very warm, very little leakage with remarkable stretch throughout. Nearly idenitcal suit is sold under Aqualung branding.
I have one and I like it, but no, it is not a semi-dry nor does it claim to be.
It does look like one and has decent seals, but the water does fully penetrate the suite within a matter of a few minutes. In a proper semi-dry, water will only penetrate part of the way even after a 60 minute dive leaving a layer of air next to your skin on your core. A proper semi-dry is also a lot most costly, more difficult to don/doff and fit is critical.
