Unfortunately the top parts of the orange housing on mine have turned black & show signs of burning or melting.
I enquired with S&B and sent a photo & they quickly replaced it for me, but didn’t respond about the possibility of it failing.
The replacement actually had an extremely tight fit which is great but I’ve had it for a while now & it’s already loosened up more than I’d like.
My sessions are never more than 5 minutes & that’s the only time the chamber is connected, plus I’m always careful not to over tighten it.
First off, this was a great observation even if it isn't a welcome one for me to read in any way. Thank you so much!
When I checked the plastic chamber housings on my hybrid I have similar burned indentions on both the upper and lower one. If you are unable to see it on your upper housing use a higher lumen flashlight or similar strong light source, and look around the lower part of the upper housing. In my case I had more pronounced, and a larger number of deformities in the plastic on the upper housing than the lower one, and this makes perfect sense given that heat rises and all that.
Honestly, this really concerns me. I don't want to be inhaling even a tiny amount of plastic gas at any time, much less deeply inhaling it, and I don't trust an o-ring on the upper housing to prevent that from happening at all. Like everyone else has been saying I have been faithful in taking the chamber off of the hybrid itself after about 5 minutes of use as the manual instructs, so my question is how long can the plastic housing be in contact with the heat of the metal chamber parts before it starts doing this?
My hypothesis is that it may not be happening during the session, and because I already have a brand-new chamber housing with no such damage laying around due to my hybrid being RMA'd I am (foolishly) going to use it to test out a possible workaround. My modified procedure will be as follows:
1. Run a normal temperature range session on the hybrid for the amount of time that I use it for (approx. 5 minutes).
2. After the session remove the chamber from the hybrid as usual, then immediately remove the o-ring from the upper chamber, and remove the upper and lower chambers from their plastic housings. Let all of the parts cool down to room temperature separately before putting it back together again to use at a later time.
3. I will monitor the new chamber housings for similar indentions in the plastic. My guess is that the upper housing will start showing the signs of heat damage sooner that the lower one will, so I will pay careful attention to it in particular.
My hope is that by doing this I will not see any damage occurring because the plastic was not exposed to the direct heat contact long enough for it to start happening. Either way it will take some time to know, and I will report my findings in any case.
On a lighter note, I finally used my hybrid at Thanksgiving for what it was always intended to do (per the manual anyway) and vaporize an aromatic herb (in this case thyme leaves) for some family members that have no idea what a volcano is, but love that kind of stuff. They were absolutely delighted with how well the device worked for this purpose, but were not as delighted by the price of it. I got several comments about how quickly it managed to make a large portion of their house smell like salad dressing.
I hope everyone is having a great holiday season, and be safe.
