James, let us know how well you like that Cloud Laser. I might have to get one of those.
I've been using it since I ripped open the package
It's real solid and shiny... feels good in the hand. It vapes as good as my MVS, same connector, same battery, same carto I'm use to. The switch doesn't appear to be 'pocket safe' like the MVS and the GLV-2 Mini... but I feel all side button mods are plagued with that issue.
I'm glad I bought it, it'll stay in my collection in the desk stand I'm making out of a 4x4x2 block of maple burl... but from the beginning it will be an alternate, home use mod.
that thing is enormous. How does it stack up to a 510?
a 510 is a connector... both my mods are based on 510 connections as are my cartos.
for reference, here is a picture of me holding the red one:
Now if you mean 'how does it compare to the cigarette sized tube battery?' well then I have to say it's like moving from an SX jazz and Peavey combo to a Sadowsky and Aguilar DB751 stack

Sure they both do the same thing... but holy crap does the Sad+Aggie sound good.
The difference is the milliampere-hour rating of the battery. I'm using 3.7v 880mAh Lithium-ion batteries (model 16340) that give me the same 'vape' all day that the cigarette tube batteries give for just the first puff or 3. Also due to the high mAh rating I can run 'low resistance' cartos... current batch are rated at 2.4ohm instead of the typical 3.0 to 3.4 of the pre filled ones. This combo give bigger output... some what similar to a 5v set up.
