A Klien is a incycler, my APIX is pretty large, but I have notice incyclers tend to be small though. I think there is no real reason. Recyclers tend to be vapor setups and vapor rigs tend to be smaller. There are incyclers and normal recyclers that range from small pendant sized rigs to 15”+ tall. My APIX is about 16”, my Hamm of course is taller. The Earl pendent is bic lighter sized and as is my Aura normal recycler pendant about the same height, but larger because of the outside funnel...
the MS Torus is normal sized.
The whirlpool on an incycler is much harder to see to.
