How would you know they actually do have the result they brandish and that it's not manipulated? That's the big question. I see a lot going on in this type of stuff that aren't true. I tried this in the past, more than a decade ago, and it never worked out. I don't know if technology has changed all that now. I used to play at local pools houses then and I would pay for "keys" as it was called then in my local parlance, after perusing their past records which were of course enviable. Each time I bought, the results wouldn't be favourable to me. I would end up losing. I believe it's the same thing with using modern tipsters. They may display winning records but in the actual sense all that is manipulated.
