This cold spark machine is quite compact and several inches shorter than the 700W unit making it lighter to transport. I have been able to pack two of them using their their cut down box shipping in a single Plano crate that is far less expensive than a Pelican style case. I do have issue with the instruction and display. The instructions are brief and not entirely clear. The 7 segment display presents the unit address, temperature and slave/master status. Unfortunately, the lead character of the display for temperature is an inverted F and the master and slave characters are not intuitive. The remote controls are not paired with each unit so when the display button (A for low sparks, B for high sparks) on a remote is pressed, all units with power on activate. There is also rather more debris from operation that expected. All this said, these units are a bargain and will certainly serve thair purpose.Read full review
