The website is supported by at least one 'twitter influencer' I would consider top 100 in this space. He's a Canadian and he's with RAS (do the math yourself, it's not that hard to figure out the name).
I registered there and the odds are very good. The software is identical to nitrobetting BUT bet105 charges half the juice and has 5x (or 20x) the betting markets.
I contacted support (live chat on website) to ask about an error setting up 2FA, had to wait for 10 minutes. Then went to Twitter, got a reply within 1 minute and talked to a real person for 10+ minutes. Error not fixed yet, but if you need help or have questions - use twitter, it's easy to get a reply.
I'd say they are legit. I'll update when I actually have experience betting and withdrawing.
