I didn't like the plastic parts on the Iatty. I don't want to poke at the iatty mind you, I think it was genius, the Ody is just more so. I also didn't like the small ceramic cup, it was too small and I could never wind a HV coil for it. Lastly, I don't know if Imeo ever made SS Iatty's but I've owned 2 and they were both aluminium and being a soft metal, could or would eventually wear. The Ody is 303 or 304 SS which is practically indestructible.
I'm sure some will pounce on me for this but like I said, I wasn't dissing the Iatty, just the the Ody is pure genius
Mine is SS........
