For Teaser players out there BetIslands gives you by far your best odds

Considering that ties are a win and that unlike 5Dimes they don't juice the favorites and even on those that 5Dimes does not juice if you were to place a teaser that ties are a win the payout is way less than BetIslands.

but the question is how reliable are they and do they pay?

NO they are not.
they want all of your money and will only send you $975 a week.  Joke
