Thats funny chopper,....I was wondering the same thing about the RM400 in US currency. I was kinda guessing it was around the MSRP of the VMAX. UUUGGGGG!!!! I cant wait till tomorrow, the anticipation is killing me. Take care everyone. ..... J

Hello....here's the update from Jack Tan:
UPDATE: 23 April 2012
It's been a week of using the Vmax. A few more things to add about it.
If you're a fan of LR gear, like LR atomizers and cartomizers....you can forget about them. Haha... Who needs them when you've got the Vmax. I did find that any atomizer from 1.5 to 1.7ohm is slightly on the hot side when used with the Vmax, even set at 3.0V, which is the lowest setting. Those who like atomizers, I would suggest using anything from about 1.8 ohm and up, as this will give you a bit more flexibility to play around with higher or lower voltages.
As for cartomizers, for Boge cartos, try the standard resistance ones with around 2.4ohm and up. LR ones are going to run a bit hot, but if you're the type that likes heat, you're gonna love LR boges on this thing.
The Vmax loves DCCs....slap a DCC at around 1.6 or 1.7ohm on this thing, and you will see it rock at around 3.7V and up. Go even higher, and it's going to blow your mind. DCCs are notorious for needing higher voltage to really get it to perform, and the Vmax just brushes it aside like it was nothing.
THE REASON THE VMAX IS ABLE TO HIT SO HARD
After days of research, measuring voltages, amps, calculating watts....I've finally found out why this thing feels like it's running at higher voltage than it actually measures out at. It's all due to the PWM, or pulse width modulation (btw, I had mixed this up with PCM in the early part of the review).
There's usually 2 ways PWM is implemented in e-cigs. Original Ego, and most of the Ego clones uses a PWM that maxes out at the voltage it is regulated at. The Akston SVR is a mod that uses PWM in this way. Example: if you set a mod with PWM at 5V, every time it pulses the power, the maximum it will go is 5V, then it goes back down to zero. This happens many times a second, so you won't feel it. Using this method, there are some cases where the performance will be a bit lower than an equivalent mod like the provari which provides constant, continuous voltage. This all has to do with the duty cycle, which is another story altogether. If done correctly, you could get almost the same performance as a constant voltage device, while reducing power consumption and giving you more vaping time on a single battery.
Anyway, the Vmax, uses a slightly different PWM method, where every time it pulses, the maximum voltage is actually slightly higher than the voltage you have set. Once the pulse goes back to zero, the next pulse will come along and the whole cycle repeats itself. What this means is, if measuring with simple equipment, you will find that the average voltage is close to the voltage you have set on the mod. If measured with something like an oscilloscope, you're gonna see the voltage going up and down multiple times every second. The average voltage is surprisingly constant from the time you stuff a freshly charged set of batteries into it, to when it's about to shut down and you're needing to change the batteries out. How high is the maximum voltage? Well, that's gonna be answered in the days to come, as I have a friend overseas who is trying to get it measured with more sensitive equipment and print out a report.
One of the disadvantages of a PWM system is that it sometimes generates a lot of electromagnetic interference. I haven't found this here, as I've not had it emitting enough EMI to actually interfere with any of my usual electrical equipment like mobile phones, computers, televisions, radios...etc. Your average mobile phone has loads more EMI, imho, as most of us have seen it making your car radio make funny noises, I'm sure, but I haven't found this happening through a whole week of use.
What does this mean to the average vaper.....well, not much, except if you're a tech head. It's just going to manifest itself as a mod that seems to operate with the same performance as another VV mod set at an even higher voltage. If done right, this is one method of increasing the performance of VV mods to the point that it can provide loads of power, while still giving you decent vaping time, as a system like this is more efficient than a constant voltage system.
The average vaper just cares about how well the mod works with his/her preferred atomizer or cartomizer. The Vmax works for me very very well so far. My provari is feeling a bit left out in the last week, I'm afraid. Some vapers who have tried it out calls the Monster a "wierd" mod...coz it seems to perform a lot hotter than any other VV mod. For vapers who are finding that setting the Vmax at the lowest voltage setting at 3V is still too hot, just use a higher resistance version of your preferred atty or carto.
Will update more when I have anything new to add.

I just got one, minus the instruction manual. Glad I had a 3 ohm tank as it defaults to 5v. Wow...
This thing has torque power like a Harley. I wonder what one would look like "Chopperised?" Maybe it's copper.
