I get to know this blog in the checknumber.com forum.
I have never tried 4d guru service before. So i can't say the are cheating.
But I listen that all of the gurus dont have this ability to predict number. They will first con you by telling that you must bank in account money to their account . Than they only give a bunch of 4d number. So i dont believe of this type of thing.
I do believe in this kumantong.
The number given is only one Set. So i can buy alot of money on one number . If the number come out we win more eventhough we bought ibet.
