I bought Extreme Burn a few years ago and like it a lot since it's got a very nice instant, visual
change. 400 Lux does also, plus it presents a convincing show of the fronts and backs of all bills,
without the need to create a gimmicked packet. If you want a bill switch that does what the others
do, but is cleaner, I highly recommend 400 Lux. You're paying for the setup and handling of this
fine effect - well worth the $25!
