S & B are SoB's... lol
They won't answer my emails, won't honor warranty, sent me no parts to fix
broken orange ring , no ceramic coating fix.
They are using the pandemic to pull a fast one I believe.
They do get to it, but expect 4-6 weeks delay on orders and around 10 days on support emails. For me shipping is also very slow takes 4 weeks total (takes a week from California to get to Canada, a week in Customs, a week from Vancouver to Montreal and a week from Montreal arrival post office to Montreal destination post office & delivery. Normally this used to take 10-14 days total from order to receiving the order, now it's ~72 days.
The new Filling Chamber & Insert is an excellent solution to the aluminium oxide issue. Essentially it's a production line quality fix that's easy to retro-fit, I don't think the so called Volcano Hybrid V2 models are any different than the previous model with the Insert latched on to the heating chamber. The insert clips on easily, does not move or fall off, has unnoticeable effect on heating efficiency and doesn't seem to wear or scratch when used with ceramic coated filling chambers (and I latch it much tighter than before). DO NOT use the older filling chambers (un-coated aluminium), once you install the ceramic coated insert (some users have shown that this does damage the ceramic coated surface).
As for the filling chamber housing, I don't get any melting plastic and I've at least twice left it on for 30 mins at 230C. Unfortunately the clips do fall off within 7 to 16 weeks depending on if you remove the filling chamber each time to brush it off and how aggressively you brush it between fillings if it is in the housing (I used to remove it each time with the first housing, because of the Al Oxide), now I only remove it to soak it in ISO once a month). The clips are not needed to use the filling chamber housing, but without them, the filling chamber easily falls out when emptying it and can lead to burning yourself if not careful (if you squeeze the housing tightly in your fingers it can 'hold' the filling chamber when turning the housing over to empty it, even it the clips are loose/gone (but with Rheumatoid Arthritis this can be difficult to put that much force on bad days). S&B will send replacement housing if asked nicely, but they do point out that this is a 'wearable part' and sort of not under any long term warranty. I do hope S&B finds a way to re-enforce these clips in the filling chamber housing or at least starts selling sets of multiple 'bottom part' of the housing (the orange part only), since the top does not wear out).
One complaint, I have, is they do not communicate efficiently... If they had been more up-front on some issues, I think they would of gotten more 'good will'. Even shipping notices do not inform you of the contents of the shipped package, no order number, no list of contents.
