3 and a half(ish) month update: The Dr. Dabber has totally replaced the MFLB as my daily driver. I used the MFLB for over 3 years and I still love it, but the convenience of the Dabber was immediately apparent from the first day when it arrived in my mailbox.
With the MFLB, it required smelly proof bags, daily charging, grinding, then more grinding (in the finishing grinder), then finally vaping, cleaning with a brush, then everything back into smelly proof bags. I had a bag for the MFLB and 2 stems, a glass jar for long-term herb storage and a plastic container for a few sessions worth (I only vaped occasionally and a 1/4 lasted me a long time, so the herb would dry out if I opened the glass jar too often). And not to forget a box for my power adapter, car adapter, and batteries. Plus a container for ABV and another small box for my two grinders and cleaning brushes. All those containers and bags added up to what looked like a full time stoner's collection.
Fast-forward to now: I have one very slim box that the Dr. Dabber came in. It has specialized compartments for the pen, 3 spare atomizers, the charger, a silicone ball (it holds my 2 types of concentrates), and the dabber tool. As for vaping, I just have to pull the pen out, vape, and put it back. Every few dabs, I'll break out that silicone ball and add a rice grain-sized amount of concentrate to the wick. No cleaning, no daily charging (I do once a month, but never actually ran out of charge), and less inhales to get where I want to go. This was such a big improvement that I haven't actually used my MFLB since the Dabber arrived.
So there you have it: for me, the Dr. Dabber is a clear winner.
---------------------------------------------------------------------------
Just one question for all of you: I haven't changed the atomizer since receiving the Dabber. I used it 3-4x/week (2 or 3 dabs per day) for the past 3.5 months, but it still works. The concentrate doesn't absorb into the wick quite as fast as it used to, but the wick heats up nicely and certainly does the job. My question is, seeing that the estimated longevity of the atomizer is around 1 month, is there any reason for me to replace it now? Since they are expensive, I just never felt like it was worth replacing yet. Is this bad for my health?
