Wanted to update how things worked out with raidentech...
After a couple of days, I finally got someone on the phone and they informed me that the smoke units are not sold by them seperately. They told me they would do an exchange of the tank for a new one, but I declined. They then agreed to refund some of my money to compensate for the failed unit. I agreed to this and in the endRaidentech has made good for me. They also said they shipped a tank antenna for me, being that it was missing from the box upon arrival. So, all is good in tankworld.
