Well, I have now done 3 days of diving in this suit. 8 dives, total.
Unfortunately, I have to report that it has a tiny leak somewhere in my right heel area.
The very first time I got in the water with it, I felt a tiny cold spot on my right heel. I thought it was a leak. But then the feeling kind of went away. I wore the suit all day - 3 dives - and never noticed that feeling again. By the time I took it off, I had forgotten about it, so I didn't specifically check for wetness.
My second day of diving, it was the same deal.
This past weekend, I did my 3rd day in it. Only 2 dives (for a total of almost 2.5 hours in the water). This time, I remembered to check out my right foot when I took the suit off. My right heel of my 150gsm Thinsulate sock was quite wet. The rest of me, including my left foot, was all dry. So, I am convinced that it does have a tiny leak somewhere in the right heel area. I think it must be really tiny to only have that little bit of water in my heel after 2.5 hours in the water.
I guess I could feel the initial leak of water coming in, then once it was in, and the water in the sock warmed up some, I just didn't feel any more water coming in.
Other than this small leak, the suit is still awesome. It has been very comfortable to dive and very comfortable to have on during my surface intervals (given that we've still had relatively cool weather here). I think it was up to around 70 all day on Saturday, when I was wearing it continuously from about 11:30 until 4:00 or so (with 150gsm full suit undies on underneath).
I have sent an email off to Seaskin to ask about how to handle this. I'll update this thread when there is further news to report.
