I have no concerns about safety of funds but there are some annoying things happening at CRIS books lately.
Particularly with moneybookers.
DSI, Bookmaker,Betmaker,Ehorse etc don't offer moneybookers at the moment but CRIS does.
They also don't take Mastercard, only Visa.
I don't currently have any funds in any CRIS books, I was playing at Betmaker recently and found out the hard way that they take a percentage of your deposit in fees when you use WU/MG and don't give commission credits like Matchbook.
Their sites are slow to load and slow moving when you want to place a bet.
For the time being I'll play at other places.
