My SI order came today. Yay?... Kind of, not really.
Unpackaged everything, screwed a cartomizer on a battery, took a drag... a terrible squealing air sound came out. I tried another carto, and another, tried screwing them on tighter, looser, nothing helped. This loud whooshing sound accompanied almost always by a separate, more terrible, squeal is dramatic and completely obnoxious! I can't use this in public, heck, I don't even want to use this by myself, extremely unpleasant and aggravating.
I tried the second battery that came with my order... Wow, not at all like the first battery, not even in the slightest. Tried every cartomizer on the second battery.. Not a problem at all, perfectly fine. Quiet and pleasant. Better vapor production I think too.
I waited about 20 mintues before I posted this message to use my Volt a bit. I am pretty happy with the one non-squealing battery. The other battery is unusable.
