I love mine. It's perfect for me and I use it at 4 1/2 volts with regular attys. Massive amounts of warm vapor with excellent flavor! The batts last me 10-12 hours ( very heavy vaporer) and the unit is beautiful in silver.
The only drawback I've read here is that it isn't as hardy as the Buzz
mod by NotCigs. It's more delicate and shouldn't be dropped a lot

I've dropped mine a few times but it hasn't broken yet! But I didn't want the Buzz because it's chubby and you have to adjust the volts with a screwdriver. The Infinity's voltage wheel adjustor works well.
I highly recommend it. The vapor is ungodly and if mine breaks, I will cry. I'd hate to use my Riva/eGo because it gives me half the vapor and throat hit my Infinity does. If I can ever afford another, I'd like a 2nd Infinity as a back up

It's the prettiest mod on the market and works excellently.
