Overall I think they are doing pretty good job
I think you cannot get 100% win rate with this service ever, but I feel like these guys are following the scene of eSports and Sports and they know what they are talking about.
I can recommend this service, especially for eSports because it is much safer betting on official LAN games and live betting. I myself did 40 bets in past 10 days from which 30 were mine alone and got 36 / 40 result, which means this kind of service can be reliable if you follow these teams and scene for a while now
DO NOT EXPECT 100% WIN RATE, 80%+ IS POSSIBLE, BUT ABOVE THAT IS ALMOST IMPOSSIBLE TO PREDICT CUZ A LOT OF TEAMS THROW GAMES AND FORFEIT.
The guys are friendly and in future we might do some business together, +++ from me
