As I am a recreational player I have found PKR to be a good place to play. Good graphics and plenty of micro-stakes games, giveaway games and freerolls to play. Not the best place to play if you are a serious grinder tho' as multi-tabling really slows down your pc.
Deposits and cashouts, in my experience, have been fast and problem free (using paypal).
Support is not the best imo. E.g, English only allowed in the chat but this rule is rarely, if ever, enforced allowing a whole range of languages to be used during games. Also verbal abuse towards other players, including racist remarks rarely gets punished. But you can easily turn chat off anyway so not the biggest of problems.
Overall a fun place to play for low stakes, recreational players.
