This is my second boomf purchase my first boomf card went off just as planned and was really dramatic.however the second one I recently received that I bought for my son didn't quite go to plan as it didn't jump out of the card like it should do, which was a bit of disappointment. Now this could be because its aimed at the younger market they have to be safer or it wasent primed correctly. I will still purchase again in the future as they are unique and get a great reaction when it jumps out at them, just a shame this one didn't go as planned.
