I don't know if it will be useful for you, but I will share my experience.
I recommend you to avoid this bookie. First of all, they are fast at limiting. They had limited me already after 1st bet, but this wasn't the key moment.
I had active bonus after limits were set. So, I continue to wager bonus with max allowed stake 9 EUR, after several bets on NBA, NHL they decided to decrease limits to 0.9 EUR max bet.
So, this was deliberated step to unable to fulfil bonus required wagering.
