I'm going to pass on the 216 as well. My Capo hasn’t leaked yet, but the feed tube wiggles around quite a bit. In a review of the 216 squonker, I saw its feed tube doing the same. In addition to the potential for leaking, I’m getting changes in resistance readings. While it’s not a huge deal on the Capo since it lacks TC, I would bet TC will be quite unreliable on the 216.
Other squonkers that I have with a feed tube (Dripboxes, Luxonic, Gbox) don’t have this problem. Ijoy really needs to re-design its feeding method.
