My last arizer solo is just sitting on my shelf collecting dust and im finally ready to part with it, Ive had the M107 and M1A models which are long gone but This one is the M1D2 model purchased in August 2012 and I think this one performs the best. I never registered it with Arizer so you can still do that. Its only been used a handful of times and has only been recharged a couple of times. Included is the stock straight stem, stock bent stem, aromatherapy bowl, 2 PVHES stems (1 is a shorty) and a PV GonG, two travel tubes, charger and the original packaging and instructions. Looking for 150$+shipping or best offer (paypal, no mention of vaporizers).
