Karatfix is a premium online tennis betting tipster who sells his tips via the Wadster Bets platform.

That means you only have to pay when you make a profit. So how does it work? You decide how many units you want to purchase. Each unit costs £10.

So you could start with 10 units for £100. If Karatsev puts up an Even money winner at 1pt stake, that would be 1pt of profit, thus taking 1 unit from your Wadster account. The equivalent of £10.

So you’ve guessed it, the more you gamble, the more profit you will make here. Wadster recommends you wager a minimum of £40 per point on this service. That’s me out.

I appreciate some punters are more than happy to wager this amount of money. Had you been a member for the past year and staked £40 per point, you would have won £1878.8 (after your pts had been deducted) which is a ROI of 6.75%.

That is on the basis you would have matched the odds quoted by the tipster. I believe Pinnacle Sports is a bookmaker choice of this tipster, so it’s important you have access to that bookmaker. If I wasn’t already out, I would be now.

Granted, this service isn’t for me, that’s ok though. There is a lot to like here and the results have been excellent. If you are happy to wager higher stakes than me, and have a Pinnacle Sports account then this tennis better service might be just what you are looking for.
