I've had a dynavap for 2 years now, and been using it exclusively since April so i'll try and share some of the things i've picked up.

Packing:
Fill your cap with weed and lightly tamp it down so theres a small gap between the top of the cap and your weed.
You dont want to pack it too tight or you risk combusting.
You can tamp it all the way down, but only do a medium temp heat cycle as it will absorb the heat much faster making a medium temp hit essentially a high temp hit.

Lighter:
You're gonna want a single flame jet lighter (i got a £8 jopoo one off amazon 2 years ago and it still works). Set it to the lowest flame height and hold the lighter in a way that just the very tip of the flame hits the cap.
You're moreso heating the cap with the hot air the lighter creates rather than the flame itself.

Heating:
Aim for just above the V on the cap, and spin the dynavap around, as fast as you can really.
Once you hear the first click, you can decide if you want a low or high temp hit; keep the flame on the V for high temp (you risk combusting if you go too hot).
Move the flame up and down the cap repeatedly for medium temp, and move the flame to the very top of the cap for low temp.
Eventually you'll get a sort of sixth sense for how hot the cap is getting and how to avoid combusting, but it takes some getting used to.

Pulling:
Once the second click happens (it's a lot louder and you can see the cap visibly move), pull lightly on the mouthpiece with the airhole completely open for the first puff. For the second puff you want to open and close the hole rapidly, and for any subsequent puffs just close the hole completely and pull as hard as you can.

Cleaning/Reclaim:
Every 10/20 hits you probably want to clean out the cap with some iso alcohol and cotton buds, but clean immediately if you combust a hit as it can ruin the taste of your next few hits.
Inside the stem of the dynavap is a metal tube called the condenser which will fill with reclaim that is essentially a low quality concentrate. You can push a cotton bud through the tube and throw it out.
But personally, I stand the cap up on a surface packed about half full with bud, hold the condenser vertically above it and heat it with my lighter so most of the reclaim drains out into the bud. then pack more bud on top, and enjoy!

Forbidden techniques:
Once you become a dynavap blackbelt, go to either recommendedvapesupplies.co.uk or tandeminnovations.de and pick up an X2 or X3. they're adapters that let you put more caps on your device so you can get massive hits.

Hope some of that helps, and good luck quitting the baccy!

bowl size depends on the model you get (newer model = bigger chamber i think), i have the 2021 M with the titanium cap and it can fit about 0.05G on a light pack and 0.1G + some kief on a tight pack.

as for hits, i get around 3 on one perfect high temp cycle, first hit being the biggest then it tapers off as you go. that typically drains all the THC from the bud in one cycle.
if you go for a lighter temp you could probably get two decent/small hits per cycle that taste really nice and get two cycles in before it's drained.
personally i always just try to drain it in one cycle with big hits, gets you completely ripped lol.

so far i haven't got any attachments for it, the base model really is all you need! the X2 is definitely on my christmas list, though i've heard it works better if you get a bigger stem + silver jackets for the tips that spread the heat evenly

and your welcome, have a good one!

97?

never thought i'd see DaD on little biggy lmao, can't wait to get in finally

if this was spice then i'd 1000% be dead or in psychosis in a mental hospital with the amount i've smoked 😂
EDIT: just got my order in and i'm cooked, thanks RealD!
