Still loving my Infinity! I has not left my side(and barely left my lips

Thought I would give a brief review for others who may be considering purchasing one.
I have the Black w/ chrome top. It is sleek and very classy looking and the anodization is very good quality. The voltage control works nice, moves easily when pushed but does not move on it's own easily. The push button actuator feels perfect, it requires just the right amount of pressure. You need to push it but it does not hurt your thumb to hold it in.
The battery life is very good. It lasts me pretty much all day and I do use it quite a bit.
The variable voltage is awesome. It provides a regulated voltage for the life of the batteries and can be "dialed in" to just the right voltage for the atomizer and juice you are using. It changes the character of the "vape" a surprising amount - different voltages provide differnet flavors and throat hit. Just simply awesome
I would like to make a few points, though - not complaints but a few things that could be possible refinements at some point. I understand well that there will always be tradeoffs as far as features versus cost and the price point of the Infinity is fabulous for the quality of a device it is. That said:
The voltage wheel: Although I personally don't care what my exact voltage is(mine registers 3.358v-6.37v) it would be very helpful to be able to quickly glance at it to make sure it hasn't moved appreciably. Even with my "old man" reading glasses on I can't make out any numbers on it, maybe with a flashlight and a magnifying glass.

If feasible, ideally I would like to see a slightly wider wheel, with numbers but also with maybe three color regions, maybe blue=3.358 to 4.3, yellow 4.3 to 5.3, red 5.3 to 6.37. (edit: I actually just fried a carto because I forgot to turn the voltage back down from 6.37v when I tested with my meter, lol)
I like the fact that the LED doesn't blind me when I use the device, But, I also think it would be nice to be able to see the "on" indicator LED while I am using the device. Additionally, it would be great to have some indication that the batteries are getting low, e.g. a red indicator LED comes on during activation when there is a 15% charge left instead of the blue LED. Also, I think a slightly more obvious indicator LED would be very helpful in those rare cases where something goes a little "funny" and the device either stops working or decides to stay on.
The end cap needs grooves - it is very "slippery" and is difficult to take off and put on. Also, ideally, I would like to see slightly longer threading on the endcap and anodized threads to allow switch "lockout". In my research, prior to deciding to purchase the Infinity, The one complaint I came across was lack of an override "off" switch and the resultant "pocket firing". i decided this was not a deal breaker for me, however, I think it would be a great addition to an already amazing device.
My only other thought is that, in a device with two Li Ion batteries in series, I would like to see "reverse polarity" protection, because, let's face it, who hasn't put a battery in backwards once or twice in their lives.
That's it for now, I hope my thoughts are taken with the intention they were given - which is merely a few items that could potentially be an improvement to an already wonderful device. I fully understand "cost benefit analysis" and some may not even like my suggestions but I thought I would throw my ideas out there.
All things considered, the Infinity is a stellar looking and wonderfully performing variable volt Personal Vaporizer and should strongly be considered by anyone who takes their "vaping" seriously.
