The Radius is a great mod, but I have no problems being critical when I pay $250US for one device. Critical, not negative or bashing. The Radius is not perfect by any stretch IME.
The $50-ish add on for the Stealth treatment is too much of an upcharge for what you get IMO. If I did it again, I would stick with what I originally ordered which was the original stainless/black. I now have the Stealth as I had to return my original Radius twice to be fixed and asked if I could go Stealth as I didn't want to potentially return the same mod 3 times across North America. It was on a FedEx truck more than in my possession. I paid the full difference in price to "upgrade" to the Stealth.
Also, my original Radius had a loose display window before and after the battery meter was sent to be "fixed" and my Stealth also came with a loose display window. Is this a common on this mod? Pretty annoying.
In any case, I hope the battery meter works properly on this one as I will snap if I have to send it back again.
I am very happy with my 8 other ProVape mods, but I am not 100% sure about the Radius yet.
