I try not to get overly sensitive with forums, its such a useful tool for sharing knowledge but that about it. I don't like forums where people force their personal opinions on you like a religious zealot. I haven't found much of that here
now that is something I DONT do. I should just ignore them. Thats a pretty bad fault I have but all I can say is *gosh dang, snaps*
Lol mag burns sent a PM to me that said "your sensitive" hahaha it was so funny.
She is correct.
Some of my response was NO IM NOT SENSITIVE DONT SAY THAT hehe jk
Oh I'm sorry I just upset more people by speaking about myself in these posts, on the internet.

oh no, nope, no one have forced their opinion on this forums, they almost always say IMO or I'm just guessing or whatever.
Getting back to the origen of this thread I offer my own observations on the subject.
Over the last 6 months I have been busy (my wife says obsessed!) with the building of many types of mod. Many combinations of battery and direct current feeds have been tried in the quest for the ultimate vape.
I had not read the concerns regarding the breakdown products of Glycerine (my favourite dilutant) and was soly concerned with maximum vapour production and atomiser "life".It soon became apparent to me that higher voltages (up to 7volts in one mod) gave amazing amounts of vapour but had the following drawbacks
Very high juice needs with a lot of wastage
Regular and often immiediate atomiser failure from burn out
Unpleasant "burnt" taste even when atomiser was wet.
I now only use a maximum of 3.7 volts (but high capacity) battery power to run my vapourisers since this approach solves all of the above problems.Now it would seem to me from my own experiences that higher voltage units,running at considerably higher temperatures are the cause of the unpleasent taste and this could be the result of high temperature breakdown products of the juice (I only drip so no cartridge contamination was present).So maybe the best way to avoid this potential problem with glycerine is to avoid it's use in high power devices.
As a foot note a well crafted 3.7volt L-ion or a 3.6volt NiMh mod can still give a much higher voltage unit a run for it's money in the vapour production "game".

I can imagine that is so. There should be an optimum voltage range, and underpowering (voltage or current) might be just as bad as over-powering. The point is to get maximum efficiency and greatest battery life. I currently use 4.8V (peak) but may use 3.7 in later mods just because there is a suitable shaped battery, in which case a bit less VG (which requires more power to vaporize) might be in order.
I would like to add this note: When I first tried a higher voltage I did get burning tastes but I am quite sure now that this had something to do with the juice; I was using prefilled standard cart flavor then. Having switched to a mostly VG based liquid, I dont get that burning taste anymore, even if vape dry. So I think it is something in particular juices that creates the burn taste, and I think it is the dry deposits that cause it, which are greater in cigarette-taste juices.

Just wondering with how much more heat the maual switches put off if anyone else vapes VG regularly with manual switch? They get so hot. Anyone know what acrolein buildup would feel like?
I burn the residue off once a week with 5V from a USB AC adaptor (ipod charger) Works great, vapour production goes through the roof and tastes much more 'pure'.
Just in case anyone missed it there is a thread alerting everyone to a new e-liquid base ingredient being manufactured by Chinese suppliers. Its Polyethylene Glycol or PEG 400. This is the polymer form of PG with an average molecular weight of 400.
I looked this up and it appears to be even less toxic than PG by about 1/3 and much less irritating to mucus membranes (PG is only slightly anyways). So far it looks like a better alternative and may be more stable under heating

I think polyethylene Glycol is the stuff used in Miralax (its a laxative) I guess it could help those that are constipated
I don't think you need to worry about glycerin on 6v. It will hardly go over 250°C same as nicotine solution. When glycerin is heated to 280 °C,it decomposes into acrolein. The first thing of over heat will kill your atomizer before glycerin decomposes into acrolein.
