Use with caution is all I could say, this stuff will chew through any unfermentable sugars, splitting them down to the more fermentable variety, problem is with it that you cannot stop it! You could end up with a beer so dry that it would be out of balance with your malt/hop profile required.
There is another thread on the site that talks about trying to crash/filter the yeast out before it finishes the fermentables created by the enzyme, but your best solution is to mash at the correct temperature and pitch the correct amount/type of yeast for the style.
