I only use few of the best and most trusted bookmakers available.

They are:

Bet365
Betsson
Centrebet
Expekt
Ladbrokes
Pinnaclesports
PaddyPower
StanJames
Unibet
 

I also highly reccomend Betfair.com but they often offer highly competitive odds.  But as Betfair is a betting exchange with very fluctuating odds, I won´t use odds found on that site.

Note that other bookies might offer better odds on tips from me than the few I use.
