Boostore Arvostelua 

Amazing. Honestly I thought this service would not be so good but it was great. Also I learned a lot from the boosters replays. 10/10

100% safe, prompt and excellent service. Would highly recommend using this service and watching the replays.

Bought Low Priority service and it was done in 3 hours. Unbelievable service would recommend. No need to worry about security issues or accounts getting stolen, they have many steps in place to insure your account cant be stolen/hacked.

Very professional and quick, thanks mates, you can buy with trust from them

Quickly and efficiently. According to the offer on the site.

They are professionals they boost my account for 1200mmr in 12 days i recommend to everyone.thx for good job!

Nice boost, fast, not 2 expansive and 10/10 Customerservice :) Order new season again Xd

Best bosting service ever, I definitely will use it next time. Cheers

great service, fast and secure. no doubt I will be back again. good job guys.

I loved how helpful they are! They are super useful and I was scared they would steal my account. But they didn't :P Their times are a bit restrictive though. Other than that, it's alright!

I was hugely skeptical of this because I fear that my account would get taken over. They increased it exactly how I told them I wanted it. I'm a support player so they adhered to playing just support heros. Honestly Its really nice cause I felt like I was stuck forever in this tier where I loved supporting but felt like other people were holding me back. I'm definitely going to use them again if need be.

Used to be one of those people who believed there was no such thing as MMR hell, it was all in your control, etc. I was wrong. After boosting, games are much easier. Boosters did a great job. I will definitely be using the service again!

I can say these people are doing a great job. I really didnt expect the result to be that good (I bought calibration). This was my third or fourth time and I thought its time to give them a thumbs up.

Beyond amazing service! Exceeded my expectations in all departments. The booster was communicative, streamed entire boost and got the job down in 1.5 days when it said it would take 5. A++ service!

Despite my worries I was allowed to leave Steam Guard on during my boosting, which enabled to have ease of mind.

good services and faster than estimated days. thanks a lot booster.net

Very satfisfied, 9/10 wins calibaration in just around 8 hours after I place the order

Awesome service! Definitely I'm gonna buy their service again!

This is my 3rd time using boostore service,best calibration/boosting service on the planet,will use their service again..
10000% recommended.

Very good and professional service. They get the service done fast and would definitely use their service again next season.
