I had a lot of difficulty refilling the LTv9/E9s the first few weeks I was using them. Then, suddenly I seemed to finally get it right, and could keep them going for days or even weeks. I was never sure whether it was me that finally did it right, or if they had changed the design to make it easier to refill.
Then I got a batch from inhaler, and half were good, lasting as long as a pack, the other half were bad, only lasting about 50 puffs. The good half were easy and reliable to refill. The bad half were unreliable, and if they workedat all when refilled, gave poor vapor, and could only be refilled a couple of times.
All of which is a long winded way of saying, you may have gotten a bad batch.
