PID controller says "220V AC", is it safe to use 120V AC?

Hello,
I bought a PID controller of dubious quality. EBAY posting said 110V to 240V but the device itself says 220V AC input voltage.
I got my money back, but it is just sitting there now so I would still like to use it.
Would there be any problems if I run 120V AC through it instead? I'm primarily concerned if it is going to be unsafe, but perhaps there could be performance issues related to it as well.
Thanks

Indeed there should not be any safety issues, but it may have performance issues. More description of the device will certainly increase the probability of getting some useful responses.
