I'm having an odd issue: my drip protected battery is now requiring more force to activate. When it was new it only required a slow, easy draw, but now I have to inhale hard and fast or draw hard in the mouth to get any action. There's a twist - it's only the echo cartos and some are more responsive than others. My CE2s still draw easy. Is this a sign that my echo atomizers are going out? None of them have been used more than one refill.
The one requiring the hardest draw is filled with Boba's Bounty (not thinned). The first filling of BB worked awesome, but after the refill I'm getting mega difficulty getting the battery to fire.
I can't get anything higher than 40% to vape well in any big cartos. A scrub of all contacts with isopropyl has always improved airflow but BB is super thick. Not much you can do in an already filled carto but I saw someone mentioning they thin theirs with rum instead of vodka. Thought to myself it may be a little sugary for long term carto use but it probably is a good thinner for that particular flavor.
