5 star service but initially I had my doubts. The website looked like I am about to be scammed but the chat box which allowed me to talk to Daniel gave me confidence that this is a genuine service. I paid for the MMR boost service with duo-queue. Pros: 1. Immortal rank boosters, so easy MMR boost. 2. Duo-que guys are professional, so no complaints. 3. 24/7 customer service through chat box in their website. 4. Boosters accommodate to your timings. 5. Delivery of 300 MMR within 7 days as promised. 6. Friendly boosters who will give you confidence in game rather than being toxic if you misplay. Cons: 1. Boosters can come online late, like 30 mins to 1 hour late, you need to have patience. Try to coordinate with them over discord before you come online. 2. Occasionally, you may loose few games as booster is great but some games booster alone cannot win when other strangers who are really in game are exceptionally bad. BUT you will gain MMR. Like maybe 1 loss for 15 games won. Go for their service without a doubt. Cheers all.
