What are the differences between the Enforcer and the Enforcer II?

The Enforcer II is an updated TM100/Enforcer. It is smaller and lighter but works the same way as the TM100/Enforcer and is just as durable.  It also contains a coin cell battery, which lasts longer than the TM100’s alkaline 9V battery.  We have completely REPLACED the TM100/Enforcer with the Enforcer II.
