I used a Joye 510 for awhile, and then on my birthday I decided to splurge a little and get myself a Vypr from vaprlife. I was wanting to try 5 volts, but I don't like the idea of stacking batteries. The Vypr 510 is a 3.7 volt device using a 14500 AA size 900 mah battery. This is the perfect device for the low resistance 510 atties from nhaler. I have enjoyed it immensely. You need something with a higher mah rated battery than the typical Joye 510 180 mah battery to run the lo-res atties, and you definitely do NOT want to use them on your 5 volt PT. I have been using them on my 510 PT with the inline 10440 battery, and haven't noticed any problems, with increased performance. Of course those atties are still kind of experimental, a little more expensive, and do not tend to last as long. You may enjoy the experience though. The wattage is somewhere in the 9 range, with the "sweetspot" being between 8 and 10 (I think the standard Joye 510 burns around 4-5 watts). Flavor is definitely better, and the vapor I JUST exhaled completely obscured my 24 inch monitor for a couple of seconds! Also, even with the lo-res atties, my Vypr battery lasts me from 5am until I go to bed at night, often around/after midnight, and still has power. I think I have only completely drained a battery once. I just throw it on the charger before I go to bed, replace it with a charged one, and by the time I get up, both are fresh. My Joye 510 battery would typically last me from 5am (actually more like 7, I was using my PT more in the morning) until around 2pm when it would die and I would switch. I vape alot at work because no one seems to care. Now, I only carry my Vypr with no extra battery, instead of two Joye 510 batteries and a USB charger.
I also put a shorty T-tip from SuperT, which is about half the size of a standard plastic 510 cart. I love the smaller size, and I drip exclusively. This is a great setup and I absolutely love it!
