Well of course there are great uses for teasers, but I am going to show you a few examples where you are actually losing money by betting a teaser even when it wins.
Personally, I hate teasers. I would just rather bet the parlay, then be stupid enough to bet a teaser. But there are times where you may want a basketball team to just WIN a game, but not cover. Having said that, I do love Denver and Phoenix tonight. But here are a few examples of the same bet done with moneyline and then a 5 point NBA teaser.

Now sure, you do get +1 with Phoenix and Denver, but that would only tie your teaser anyway. More importantly, you would have Houston at -3 and San Antonio at -2.5. Those points could kill you.
Here is another example using a 2 team teaser of 4 points.
