Why? Uniseals doesnt hold pressure? Leak problems? Thanks in advance!

@Highforfive You can get Uniseals in Europe here: http://unisealshop.com/page.cfm?page=1 They also sell on amazon and ebay. I'm also making plans for a RDWC build. How these uniseals perform? Do they work flawlessly? I have seem many thoughts about it and would like to hear yours :)
