Yeah, HCigar doesn't do much of anything with configuring the device. They pretty much slap the board in, upload their logo, and that's about it. Make sure you set your internal resistance too. I'm not really going to complain about it though. It's all easy enough to do in EScribe. I have a VT75 Nano and it's a great little mod, but my main complaint is the screw on battery cap. Did they happen to change that with the VT75C or is it the same shitty screw on cap? For the Nano I've just learned to leave the battery in and charge it through the USB port. And at least Fasttech sells spare C-Frames and battery caps for it. I've already had to replace them once and will probably have to replace it again if I ever want to change out the battery.
Neither are the DNA75C chip, but I'm glad I found the Lavabox M. Picked one up for $71 several months ago and I've been really digging it. Then a week ago I picked two more up during Volcano's 4th sale for $45 each, but I had a 30% off coupon that made the mod $32 and some change. So the VT75 Nano will be the backup to my backups backup. Or if I just need a 'junker' mod for some reason, it's not a bad junker to have around if you ask me.
