I've played on PKR before, it's very trustworthy, just far to slow and more graphics oriented than poker.
I actually know one of the commentators on the show who does the final tables, which are broadcasted on poker T.V on Sky so I have 100% faith in the actual site.
Everything is just so slow, because of the graphics so it kind sucks for that very reason only. As stated, the games are soft because it's promoted on T.V here in the UK which attracts many of the newbies.
