blueangels5, try reading in this section:
Blu Electronic Cigarettes - E-Cigarette Forum
If the blu suits your needs, ie: size, similarity to a regular cigarette, etc, then use it. There is a lot of blu bashing on this forum, but many people find that it suits their needs. ANY PV is the best one if it works for YOU.
And before anyone blasts me about what I've tried, I have: 801 manuals/autos, and an 801 PT, A sparkplug in 801 and 808 cartomizer, a copper pipe mod, a nicobox, a blu, and a volcano kit, and PT for the Volcano.
They all serve their purpose at different times, and each one has their positives and drawbacks. Use what works for YOU, not what someone else tells you you should usse.
