Upon further research, I keep hearing that the threads are crap on a vamo. I really don't want to keep paying the $ over and over if I'm going to have to keep replacing it. Thoughts?
Threads are a weak point on Vamo and Evic.
They have survived plenty well enough on the SID (smok) mod.... but I'm not sure SID is free from troubles (nor is SVD either)
Nothing is 100% reliable. MVP is the least complained about (although the centre pin gets pushed down too easily, and it's a box)
IF I was choosing today, I'd either go Provari (yes, I know...kind of scary) or simply buy a cheap SID or Vamo on the "understanding" that it might only do 6 months. Better to get 6 months on a $50 device, than 5 on a $120 Evic.
