I have the 454 and used the FX700 in a tourney recently. The distance is pretty similar, but the 454 has a much better feel to the barrel and a larger sweetspot.
Depends on the location and direction of the crack, some will last a while, some break fast...but it was only 25 bucks and returnable, nothing hurt there.
The reveals seem to be hit or miss, some love them, some hate them. But, considering the price you got it for, you didn't get hurt, and the return is worth the investment.
