From what i have read the ziegeli zmax is not much better then the vamo as far as construction, and seems to get about as many failures happen with it as the vamo.. from reading forums.. unfortunatly these chinese made mods are a crapshoot on construction some are awesome some suck... one of my vamos is a bit wobbly with the internal mechanics (chip, screen, button) while the other is compeltely solid feeling. I like that with the vamo it can be used in two size configurations full and mini that was my selling point on them along with the 50 dollar price tag. This is just my opinon though, no for mechanicals i havent heard much on the stainless steal bolts but the plastic ones are just plain crap, ya there 30 bucks but they not even worth that in my opinion.. I really do want to get a SB at some point and a provari I have only heard really good thing about either of those items but the price tags are pretty steep on both as well.. however i do have a birthday coming up

and just whispered into certain ear what i want for my bd

....heheh and i just showed em to my honey if i get one of those my pv count will be 4 and i can also whisper another birdy into my mommies ear

for a SB who cares if i get duplicates if they both get me a provari or SB thats just means i has spares OMG i am now really excited snicker

... BWAHAHAHAH evil plan hatched!!!
