General:
Playtech is based in the Netherlands. The software looks pretty good and there is a large variation of games to choose from. Many Playtech casinos have Live Dealers, but if you are looking for Live Dealers, you should rather choose to play at CasinoWebCam. The Live Dealer software at Playtech is pretty blurred, which is a shame, as it hides the gorgeousness of the lady-dealer. ;-)
More and more casinos are choosing the Playtech software, but their signup offers are mostly pretty bad. The signup bonuses might look very attractive at a first sight, but the problem is that they are usually Sticky bonuses.
Many Playtech casinos are also slow to payout winnings and some of them have a tarnished reputation.
Software Rating: Software beauty and game variation are plusses, everything else are bad points:
