Definitely recommend the Volt. I actually use it every day. It's the only method I have at the time. I have been using it since I started vaping in April. I use the shorter 65mm batts, but wish I would have gotten the 78s. The Blu disposable is actually larger than the volt system, so you definitely will have something closer to the size of analogs. Everything passed along so far about the Volt is pretty much dead on. The battery life is awesome for being so small. I get about 2.5 hours out of the 65s with a pretty steady amount of vaping. The product choice from Smokeless Image is amazing and the customer service is the best, bar none. If going with a kit, I recommend getting the mega charger as the option. It has a place for a fully assembled pv, a spot for charging an extra battery and holds 3 cartomizers. It is rechargeable itself and will take care of you for the entire day if not longer since you don't smoke much.
I didn't realize the blu disposable was bigger than the volt. Is that just the 65mm or does that include the 78mm too?
I was looking at that exact kit and had come to the same conclusion concerning the mega charger.
Thanks!
