I'm in heaven right now, seriously.
This thing is everything I hoped for...and more. You know how the first drag off a newly topped off carto, on a freshly charged battery, tastes? This is so much better! It's a deep, moist, flavorful hit with plumes of vapor...every time. I'm getting more than a day's worth of battery life, and I've only gone through 3 mils of juice in two days of moderate vaping.
I tried both my brand new LR306 and LR510 Cisco 2ohm atomizers, vaping my everyday Cafe Mocha, but noticed very little difference between the two. I'll need to do some more comparisons there.
The Grand is definitely built like a tank. Its body is machined out of a solid block of aircraft grade aluminum and beautifully anodized. It is quite a conversation piece. Its smooth finish feels good in your hands, button placement is very comfortable. I didn’t realize the button rotated to a locking position to prevent accidental firing, a nice feature for sure, but also the source of a few moments of panic as I sucked nothing but air several times!

"Sqwonking" the bottle is easily accomplished through the provided opening in the door. The door slides upwards or downwards within a groove on either side of the opening in the main body, and is held in place by a couple magnets.
It is a bit heavier than I anticipated, weighing in at just over 6 ounces with a battery and full bottle of juice. Also, due to the nature of all bottom-feeders, there's a noticeable bubbling or gurgling noise when you're vaping. I can see how this might not be for everyone. You definitely get strange looks while using this baby. My wife looked over at me and told me that I "look weird." She called me a "box-sucker."

Unfortunately, I think that type of reaction has to be expected until personal vaporizers eventually become more widely accepted...and understood.
I loved my V4L kit and it served me well, it helped me finally kick the habit once and for all. But the Grand just takes the experience to a whole new level of enjoyment. Thus, my V4L kit has been relegated to backup duty for the foreseeable future. I had easily already broken even with what I had spent on vaping vs. what I would have spent smoking, so this was my way of rewarding myself for a job well done. I couldn't be happier.
I'm really looking forward to stepping down another nic level just so I can vape a little more with my new toy!
