Received my Bloog MaxxFusion a couple of days ago, and was first real excited. And it was great with the Bloog cartos. However, when attaching other cartos (V4L) it isn't as good as my other KR808D 1 batteries. Still have to do several primer puffs, and not a lot of vapor. Any others finding this problem? I think maybe it is the Bloog cartos that are great so do not know what I paid for.
